HEALPix v1.20: Patch #01
 
On March 1st, 2003, the patch #01 to HEALPix 1.20 has been mailed to all registered users. It addresses the following bugs (*) and includes some non-critical improvements (*).
 
Fortran 90
 
  Affected File     Routine(s)     Remarks
 
src/f90/anafast/anafast.f90   *
 anafast facility   error on pixel masking when dipole removed; inadequate format for dipole coordinates
 
src/f90/mod/alm_tools.f90
src/f90/mod/alm_tools_omp.f90 		  *
 create_alm   crashed because of round-off error on polarized power spectra (Reported by Carla Sbarra)
 
    *
 generate_beam   upgraded to deal with WMAP beam transfer function files
 
src/f90/mod/fitstools.f90   *
 getsize_fits   gave error messages when run on FITS ASCII table
 
    *
 input_map,
read_bintab 		  were victims of one Sun compiler bug
 
src/f90/mod/pix_tools.f90   *
 remove_dipole   gives wrong results when applied to cut sky; error on pixel masking
 
src/f90/mod/udgrade_nr.f90   *
 udgrade_ring   intent violation of map_in
 
src/f90/smoothing/smoothing.f90   *
 smoothing facility   wrong value of output ORDERING keyword
 
Fortran 90
 
  Affected File     Routine(s)     Remarks
 
src/idl/fits/getsize_fits.pro   *
 getsize_fits   variable fake unknown
    *
 getsize_fits   gave warning when dealing with WMAP maps
 
src/idl/fits/read_fits_map.pro   *
 read_fits_map   upgraded for faster reading of WMAP maps
 
src/idl/fits/read_fits_s.pro   *
 read_fits_s   upgraded for faster reading of WMAP maps
 
src/idl/misc/init_healpix.pro   *
 init_healpix   gave wrong date for release date
 
src/idl/toolkit/ud_grade.pro   *
 ud_grade   did not accept 2 column WMAP maps
 
src/idl/visu/oplot_graticule.pro   *
 oplot_graticule   did not combine correctly changes in astrophysical coordinates with arbitrary rotation
 
src/idl/zzz_external/astron/fits_close.pro
src/idl/zzz_external/astron/fits_open.pro
src/idl/zzz_external/astron/fits_read.pro
src/idl/zzz_external/astron/tbget.pro
src/idl/zzz_external/astron/tbinfo.pro 		  *
 new routines   added for faster reading of WMAP maps
 
NOTE: If you edited any source files in the original HEALPix 1.20 package (and specially among those listed above), make sure to create a copy of these files before proceeding with the installation of the patch.
