The latest versions of the HEALPix package (2.15* & 2.14) offer the following new features:

Bug corrections and Improvements in Versions 2.15 and 2.15a (2010-06)

Fortran 90

  • remove_dipole: removed confusing warning messages about unused masks and weights.

IDL

  • cartview, gnomview, mollview, orthview:
    • export of projected map into a FITS file (FITS keyword), or an IDL array (MAP_OUT option) now available with all viewing routines,
    • added CHARTHICK support; accept array of OUTLINE structures (if they have the same fields)
    • correction of a bug (in loaddata_healpix) that was affecting the behavior of these viewing routines after consecutive calls with very partial cut-sky and then full-sky data sets [2.15a];
  • remove_dipole now outputs the monopole and dipole covariance matrix;
  • write_fits_map, write_tqu, write_fits_sb: BAD_DATA keyword added to FITS header;
  • update of astron library routines (24-May-2010) for improved WCS support.

Bug corrections and Improvements in Version 2.14 (2010-03)

Fortran90

  • correction of a numerical bug in alm2map_der routine that was affecting the accuracy of the Stokes parameter derivatives $\partial X/\partial\theta$, $\partial^2 X/(\partial\theta\partial\phi\sin\theta)$, $\partial^2 X/\partial \theta^2$, for X=Q,U produced by synfast (bug detected by Wen Zhao, Cardiff University). See ''Fortran Facilities'' Appendix for details.

IDL

  • cartview, gnomview, mollview, orthview:
    • OUTLINE=, GRATICULE=, IGRATICULE= work again with virtual windows (WINDOW<0)
    • YPOS= and RETAIN= keywords active again
  • orthview: fixed problems with /SHADE keyword, which now outputs 8-byte (instead of 16-byte) PNG files
  • ianafast, ismoothing: fixed problem with processing of polarized maps stored in memory.
  • ud_grade: improved handling of flagged pixels on Double Precision input maps
  • remove_dipole: COORD_IN= and COORD_OUT= now accept lower case values; /SILENT keyword added.

Java

  • 64 bit java-HEALPix, supports Nside up to = 229 = 536870912
    • now fully implemented
    • much faster pixel queries (eg query_disc)
  • jhealpixSmall.jar: new smaller jar containing only main classes to be used into other applications or from the web (applets, $\ldots$)
  • Java3d: upgrade/degrade fixed; color bar update fixed
  • many others minor issues and javadocs fixed
