fitsTcl: A TCL interface to FITS Files

fitsTcl is an extension to the TCL language, providing simple access to astronomical data stored in FITS file format. fitsTcl implements a Tcl interface to the CFITSIO library, developed by the HEASARC (High Energy Astrophysics Science Archive Research Center) at the NASA Goddard Space Flight Center. fitsTcl is primarily distributed as part of the fv FITS file editor, but it is also available as a stand-alone source code package below. The latest version is 2.5, released December 2022.

For more information, please see the User's Guide.
