The Space Telescope Science Data Analysis System (STSDAS) is software
for calibrating and analyzing data from the Hubble Space Telescope
(HST). STSDAS includes the same
calibration routines as are used in the routine data processing
pipeline, as well as general-purpose tools and enhancements to the
Image Analysis and Reduction Facility (IRAF).
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, including
most Unix and VMS systems.
The CL provides a wide range of functions typically provided by an
operating system, and uses a syntax similar to Unix. Some of the CL
features include input/output redirection and piping,
command buffers and history editing, minimum matching of commands,
host-independent file naming, parameter range checking, background and
batch processing modes, an integrated online
help system, and a script authoring environment.
