Programmers will inevitably make use of this datatype (whether or not the added precision is strictly required) and will sometimes want to store the results to a FITS file. CFITSIO provides simple high-level routines for reading and writing FITS files that insulate the programmer from the internal complexities of the FITS format. No releases published. More importantly what does the histogram look like, you can see that in the above programs, this will tell u alot. Although FITS was originally designed for transporting image data on magnetic tape (which accounts for the ‘I’ and ‘T’ in the name), the capabilities of the FITS format have expanded to accommodate more complex data structures. General HEASARC FITS Almost all the files that are input to, or output from, the Fermitools are FITS files.
