@Next time the wcsprm struct needs changing:
-------------------------------------------
- ...



TODO - more stars mean higher priority
(these need to be reviewed and prioritised):


Autoconf
--------
* Define macros for BEGIN_C_DECLS and END_C_DECLS (for C++) and use them in
  the headers (autoconf book, Sect. 7.1.3).

* Function definitions (autoconf book, Sect. 7.1.4).


C library (defects)
-------------------
** wcshdo(): Handle CUBEFACE and STOKES axes.

* wcsmix(): Fix polar case.

* wcsbth(): Flag axis or column numbers with leading 0, e.g. 0CRPX03?

* awavwave() and waveawav(): Check the range of validity of the refraction
  equations when computing to/from AWAV.

* tabs2x() extrapolation for multi-dimensional tables.


C library (components of the standard yet to be implemented)
------------------------------------------------------------
Paper I:   Sect. 3.5: Coordinate system cross references for bintable image
           arrays - wcsbth().  WCSXna -> WCSTna, e.g. WCSX13A -> WCST12B
           Straightforward in principle.  Requires that wcsbth() match the
           WCSXna keyvalue with the (arbitrary) WCSTna keyvalue and create a
           copy for WCSXna of the wcsprm struct created for WCSTna.

Paper II:  Complete.

Paper III: Appendix A: Implement VELANGLa.  While it should be straightforward
           to implement the equations, changes are required to the API of some
           spc and spx functions.  Also how to handle multiple roots?

Paper IV:  Support for distortions in bintables - wcsbth().  Straightforward
           in principle.  Requires parsing distortion keywords for bintable
           image arrays and pixel lists.

           Support for distortions in wcscompare().  Testing for an exact
           match should be straightforward.

           Sect. 3.4: Implement Lookup distortion type.  Implementation is
           similar to -TAB coordinates but the distortion array must be read
           from an image extension so requires help from CFITSIO or similar.

Paper V:   Complete.

Paper VI:  Complete.

Paper VII: Sect 4.1.4: TREFDIR/TRDIRn is only partially implemented.  TREFDIR
           contains references to (i.e. the names of) two other, arbitrary
           keywords (e.g. RA_NOM and DEC_NOM) that contain the reference
           longitude and latitude.  Currently, a user would have to parse the
           TREFDIR keyvalue returned by wcspih() and then use fitshdr()
           subsequently to retrieve the keyvalues.  Probably best left as is
           with a comment added to the prologue of wcs.h.


C library (extensions)
----------------------
* Investigate the possibility of allowing output arrays to be set to input
  arrays, e.g. prjs2x(prj, nx, ny, sxy, sxy, x, y, x, y, stat).

* Deal with r0 < 0.

* C++ wrapper classes.

* Interface to SoFA for rewriting WCS keywords to change coordinate systems
  and Doppler frames.

* Routine returning, for any projection, the sky solid angle subtended by a
  pixel (Patrick Sizun, email 2005-01-04; Jürgen Knödlseder, email
  2009-02-23, and others).

* Routine returning, for any projection, the value of the Jacobian at any
  point.

* cutfwd() & cutrev(): given a path defined by a (possibly parameterized)
  function of pixel coordinates (for example, a slice) cutfwd() accepts either
  longitude or latitude and returns the pixel coordinates, cutrev() accepts
  one or other element of the pixel coordinate and returns the longitude and
  latitude.


Testing
-------
* Create a more complicated test header for testing wcsbth.

* Verify and distribute the FITS test file generated by twcstab.

* In tcel2, some of the graticules are missing their parallels of latitude.

* Augment twcstab.c with an optional coordinate grid plot.

* Change Fortran/test/ttab2.f to match C/test/ttab2.c.

* Write a C++ test program.


PGSBOX (defects)
----------------
*** Part of the graticule is missing from the first plate carrée test.

*** Fix gaps in pgtest CYP grid lines at +/-180.

* pgsbox/pgwcsl doesn't properly handle the divergence of Mercator's
  projection.

* pgwcsl doesn't handle discontinuities between the faces of the quadcube
  projections - the native longitude doesn't jump in passing between faces.

* pgsbox/pgwcsl can't handle pixels that lie outside the principle range
  of native longitude [-180,180].  There doesn't appear to be much hope of
  handling this.


PGSBOX (extensions)
-------------------
* Generalise pgwcsl to 2-D slices of an N-D image, e.g. an RA-Vel slice
  through an RA-Dec-Vel cube.

* Define macros with informative names for status return values.  E.g.
  status == 1 from wcs.c functions would be #define WCS_NULLPTR 1.

* New "fixer" function to translate non-standard longitude/latitude pairs,
  e.g. "LONG"/"NPOL" -> xLON/xLAT or yzLN/yzLT (Pan Chai email, 2008/02/26).
d27 2

* Check the range of validity of the refraction equations when computing
  AWAV.
d72 1
a72 14
* Implement VELANGLa from Paper III - requires changes to the interfaces
  of some spc and spx functions.  Also how to handle multiple roots?

* Function to convert coordinate systems, e.g. FK5 to ICRS (Neil).

* FITS WCS verifier (Bill Pence, email 2004/12/17).

* Investigate the possibility of allowing output arrays to be set to input
  arrays, e.g. prjs2x(prj, nx, ny, sxy, sxy, x, y, x, y, stat).

* Investigate the speed of the wcstrig wrappers (Emmanuel Bertin, email)
  versus the macro implementation.

* Implement Paper IV.

Low priority
------------
* Fix wcsmix() polar case.

  2009-02-23).

* Routine returning, for any projection, the value of the Jacobian at any
  point.


WCSLIB
------
* Deal with r0 < 0.

* cutfwd() & cutrev(): given a path defined by a (possibly parameterized)
  function of pixel coordinates (for example, a slice) cutfwd() accepts either
  longitude or latitude and returns the pixel coordinates, cutrev() accepts
  one or other element of the pixel coordinate and returns the longitude and
  latitude.

* C++ wrapper classes.


PGSBOX
------

TODO-1 -----------------------------------------------------------------------
d3 3
a5 3
WCSLIB
------
* Deal with r0 < 0.
d7 2
a8 1
* CDELT + PC arguments -> CD.
d10 1
a10 1
* Generalization of TAN projection.
d12 2
a13 1
* Vector implementation.
d15 2
a16 1
* Pixel regularization image.
d18 2
a19 5
* cutfwd() & cutrev(): given a path defined by a (possibly parameterized)
  function of pixel coordinates (for example, a slice) cutfwd() accepts either
  longitude or latitude and returns the pixel coordinates, cutrev() accepts
  one or other element of the pixel coordinate and returns the longitude and
  latitude.
d21 1
a21 1
* C++ wrapper classes.
d23 4
d28 1
a28 4
PGSBOX
------
* pgsbox/pgwcsl doesn't properly handle the divergence of Mercator's
  projection.
d30 1
a30 2
* pgwcls doesn't handle discontinuities between the faces of the quadcube
  projections - the native longitude doesn't jump in passing between faces.
d32 1
a32 3
* pgsbox/pgwcsl can't handle pixels which lie outside the principle range
  of native longitude [-180,180].  There doesn't appear to be much hope of
  handling this.
a34 1
TODO-2 -----------------------------------------------------------------------
a65 2
* FITS WCS header parser for bintables.

a74 5
FORTRAN library
---------------
* Change Fortran/ttab2.f to match C version.

a109 99
  MacOSX
    2005/10/28  Jeremy Brewer		...OK (flex)
    2006/06/08  Paul Kunz		...OK (flex,install)
    2006/08/07  Matthew Whiting		...OK (flex)
    2006/05/16  Robert Lupton		...OK (shlibs,signbit,etc.)

  Solaris 2.8
    2005/12/14  Brian Irby		...OK (gmake)

  64-bit Linux
    2006/05/31  Ger			...OK (%x formatting)
    2006/08/11  Paul Kunz		...OK (flex, %x)

  OSF/alpha 4.1
    2005/12/14  Brian Irby		...OK (flex,OSF C compiler quirks)

* Clean compile (gmake cleanest ; gmake ; gmake tests):
     linux      (grus,      Debian sarge, gcc/g77 3.3.5)
     linux      (etch,      Debian etch,  gcc 4.1.2, g77 3.4.6)

     sun4sol    (atlas,     SunOS 5.8,    cc/f77 WS6 v5.1)
     sun4sol    (lynx,      SunOS 5.9,    cc/f77 WS6.2 v5.3)
     darwin_ppc (crab,      Darwin 8.8.0, gcc/g77 3.4.6)

     linux64    (delphinus, Debian etch,  gcc 4.1.2, g77 3.4.6)

* Configure/build: conditionally link twcstab, twcshdr and wcsgrid to
  getwcstab.o if fits_read_wcstab() is not present in CFITSIO.

* Configure/build: check for availability of flex and its version.  If
  the required version is not available then substitute pre-generated
  output using flex 2.5.33 (in Debian etch).

* Configure/build: Fortran name-mangling.

* 32-bit alignment in the data structs - all OK.

* Linux compiler warnings generated with 'gcc -std=c89':
    ISO C does not support the `%Ld' scanf format (fitshdr.l,
      fitshdr_f.c & tfitshdr.c) - replace with %lld.
    String length '535' is greater than the length '509' ISO C89
      compilers are required to support (tcel2.c) - fixed.
    string length '809' is greater than the length '509' ISO C89
      compilers are required to support (HPXcvt.c) - ignored.
    'yyunput' defined but not used (fitshdr.l) - added '%option nounput'.
    Implicit declaration of function 'setlinebuf' (tbth1.c, tfitshdr.c,
      tpih1.c, tpih2.c, twcstab.c) - use setvbuf() instead.
    Implicit declaration of function 'fileno' (wcsulex.c, wcsutrn.c) -
      only in flex-generated code so should be ok.

* Linux64 compiler errors generated with 'gcc -std=c89':
    Conflicting types for 'read' (wcsulex.c, wcsutrn.c) - old version
    of flex (2.5.4) on delphinus needed upgrading (to 2.5.33).

* Linux64 compiler warnings generated with 'gcc -std=c89':
    Format '%lld' expects type 'long long int *', but argument 3 has
      type 'int64 *' (fitshdr.l, tfitshdr.c) - fixed configure.ac.
    ISO C forbids conversion of function pointer to object pointer type
      (casts in the various *prt functions) - ignored.

* 64-bit alignment in the data structs.
    cel.h: celprm		OK
    spx.h: spxprm		OK
    lin.h: linprm		Fixed
    prj.h: prjprm		Fixed
    spc.h: spcprm		Fixed
    tab.h: tabprm		Fixed
    wcs.h: pvcard		OK
           pscard		OK
           wtbarr		Can't be changed because of CFITSIO
           wcsprm		Fixed
    fitshdr.h: fitskeyid	OK
               fitskey		OK
    getwcstab.h: typedef struct	Can't be changed because of CFITSIO

* Function wcshdo() to write out a wcsprm struct as a FITS header.

* wcspih
    2007/06/07  Jim Lewis (removal of cards from header)

* Check thread-safety - OK except for Flex code.

* Each header file should reference the README file.

* wcsbth()
  + Implementation completed for bintable image array keywords and pixel
    list keywords (single image).
  + Image header keyword inheritance mechanism in bintables.
  + Implement colsel.
  + Implement keysel.
  + Check that DATE-AVG DATE-OBS MJD-AVG MJD-OBS OBSGEO-X/Y/Z and their
    bintable equivalents, DAVGn DOBSn MJDAn MJDOBn OBSGXn OBSGYn OBSGZn,
    do not, by themselves, cause a wcsprm struct to be created.

* Memory leak in flex-generated code.
    2005/10/21  Ger (valgrind)
    2006/12/28  Jim Lewis
  Fixed.

------------------------------------------------------------------------------
Jobs for v4.4:
d119 1
a119 19
* wcsbth
  + Create a more complicated test header for testing.

* CUBEFACE and STOKES handling in wcshdo().

* wcsbth
  + Implement bintable cross-references:
    WCSXna -> WCSTna, e.g. WCSX13A -> WCST12B (fully specified)
  + Flag axis or column numbers with leading 0, e.g. 0CRPX03?

* Check that GLS is translated properly to SFL (probably isn't).

* Write a C++ test program.

* Fix gaps in pgtest CYP grid lines at +/-180.

* Change test suite to report summary "pass" / "fail" where possible.

* Interface to SoFA for changing Doppler frames and coordinate systems.
