CFITSIO - A FITS File Subroutine Library Quick Start Guide C Reference Guide CFITSIO is a library of C and Fortran subroutines for reading and writing data files in FITS (Flexible Image Transport System) data format. CFITSIO provides simple high-level routines for reading and writing FITS files that insulate the programmer from the internal complexities of the FITS format. CFITSIO also provides many advanced features for manipulating and filtering the information in FITS files. What's New: 10 April 2009 - A beta release of a thread-safe version of CFITSIO is available (see link below). This is compatible with multi-threaded application programs that use either the POSIX pthreads interface, or the OpenMP interface. 18 March 2009 - CFITSIO Version 3.14 released, containing minor enhancements over the previous 3.13 version. For a complete list of changes, see What's New in this release. This release also includes the latest 1.1.3 version of the fpack and funpack image compression utilities. 20 August 2008 - new release of the fpack and funpack FITS image compression utility programs, version 1.1, is now available. The default Rice compression algorithm typically provides 30% better compression and is faster than using GZIP to compress a FITS image file. July 2009 - New version 5.2.1 of the Fv FITS file viewer and editor is available . New version 2.0 of CCFITS has been released. CCfits is an objected oriented interface to the CFITSIO library written in C++. Download the CFITSIO Software Library: NEW!  Beta 3.18 version (thread-safe). Build the cfitsio library with > ./configure --enable-reentrant > make See the "readme.threads" file that is included with the sample test programs for more information on using this version of CFITSIO with multithreaded programs.
