Description:
Modern astronomical cameras capture data in a format called a FITS (Flexible Image Transport System) file. FITS files cannot be opened by many common image processing programs. FITS Liberator 4 is a program that opens FITS files and saves them in a format the can be opened and manipulated by common image processing programs. In this podcast, Robert Hurt (IPAC) talks about FITS files, the history of FITS Liberator, how you can use FITS Liberator 4 to create your own images and some sources of astronomical data.
