[fitsbits] WCSLIB 4.2
Greetings, WCSLIB 4.2 is now available from http://www.atnf.csiro.au/~mcalabre. The main developments in this release a several bug fixes for -TAB handling, enhancements to -TAB handling, and completely revised installation procedure based on GNU autoconf. Change notes for the C library are appended. Mark Calabretta ATNF WCSLIB version 4.2 (2005/09/23) ------------------------------- * Brought the installation process under control of GNU autoconf, the top- level makefile now builds and tests everything, and the C library has a config.h in which WCS_INT64 is set. Added an INSTALL file. * Merged the FORTRAN, C and PGSBOX READMEs into one top-level README. * Extensions for -TAB coordinate handling: in tabx2s() and tabs2x(), allow extrapolation by half a cell at either end of the index and coordinate tables; fits_read_wcstab() (in getwcstab.{h,c}) allows TDIMn to be omitted for 1-D lookup tables for which it has the form '(1,K)', i.e. describing a degenerate 2-D array; wcsprt() now prints the wtbarr structs in wcsprm. * Bug fixes for -TAB coordinate handling: in tabx2s() and tabs2x() the incorrect indexing variable, m instead of i, was used for tab-crval[]; wcsp2s() and wcss2p() returned prematurely in the tabular coordinate loop; in wcstab(), removed an extraneous assignment to wtbp-kind for index arrays. * In wcsp2s() and wcss2p(), elements of the stat[] vector that had been set were being reset incorrectly to zero. The stat[] values are now set as flag bits for each coordinate element. * Added cdfix() to the wcsfix() suite to fix erroneously omitted CDi_ja cards. * PGSBOX is now compiled into a separate object library, and is installed alongside WCSLIB. * Eliminated several instances of non-ANSI C library functions and header files and some residual K&R C usage. The Sun C compiler complained about const int definitions of initializers used in variable declarations in some of the test programs; changed these to preprocessor macros. |
