HISTORY This is a software package for HEALPix, the Hierarchical, Equal Area, and iso-Latitude Pixelation of the sphere, which was originally devised in early 1997 by Krzysztof M. Gorski at the Theoretical Astrophysics Center in Copenhagen. Early development of the HEALPix concept and initial implementation was made in the spring of 1997 in collaborative work of KMG, currently at JPL with Eric Hivon, currently at IAP. Benjamin D. Wandelt, currently at IAP, has contributed critically to the further development of HEALPix and related mathematical methods. The HEALPix-based methods contained in the present package, their implementation in Fortran90, IDL, C, C++ and java routines and codes, and documentation were developed jointly by: Anthony J. Banday (banday@mpa-garching.mpg.de), Matthias Bartelmann (mbartelmann@ita.uni-heidelberg.de), Hans Kristian Eriksen (h.k.k.eriksen@astro.uio.no), Krzysztof M. Gorski (krzysztof.m.gorski@jpl.nasa.gov), Frode K. Hansen (fhansen@mpa-garching.mpg.de), Eric Hivon (hivon@iap.fr), William O'Mullane (womullan@skysrv.pha.jhu.edu), Martin Reinecke (martin@mpa-garching.mpg.de), and Benjamin D. Wandelt (bwandelt@iap.fr). The HEALPix package is available at this address: http://healpix.sourceforge.net COPYRIGHTS Copyright 1997 by Krzysztof M. Gorski for the HEALPix design and logo.
