Software Tools

The STIS Exposure Time Calculators (ETCs) are online tools that predict the count rates and S/N in various observing modes given specified source characteristics.

The Target Acquisition Simulator (TAS) applies the actual STIS target acquisition algorithm to a user supplied image.

The Astronomer's Proposal Tool (APT) is the general proposal planning tool for all HST instruments. The Bright Object Tool (BOT) in APT is now availble for STIS CCD and STIS MAMA observations.

Requests for STIS data from the HST Archive always return data reprocessed with the current version of CALSTIS and the best available reference files (see OTFR). In many cases, it is easier to let the archive pipeline reprocess data for you. If standard pipeline processing is inadequate, however, CALSTIS may be downloaded and run locally.

STSDAS is an IRAF package that includes CALSTIS, which is used to process STIS data. A history of modifications to CALSTIS is available. For general help with STSDAS tasks, visit the STSDAS Help Pages.

Additional STIS specific IRAF scripts supplement the intrinsic capabilities of CALSTIS.

The IDL package MULTISPEC can be used to extract multiple point-source spectra from slitless spectroscopic data. Here the MULTISPEC Handbook

STIS point spread function (PSF) images may be downloaded from a PSF Library, based on target color, HST focus, STIS filter, detector, and position on the detector.
