STSDAS

STSDAS

The Space Telescope Science Data Analysis System (STSDAS) is a software package for reducing and analyzing astronomical data. This package is layered on top of IRAF and provides general-purpose tools for astronomical data analysis as well as routines specifically designed for HST data.

STSDAS runs in the IRAF environment. IRAF provides the user interface (command language, or CL) and general purpose graphic and image display facilities. Because STSDAS is layered on IRAF, the system runs on any computing platform for which an IRAF port is available.
