The Astronomy Tools and Applications Branch of the Space Telescope Science Institute wishes to announce the availability of version 3.4 of the Space Telescope Science Data Analysis Software (STSDAS). Concurrent with the STSDAS release, we have also released v3.4 of the TABLES external package.

The Astronomy Tools and Applications Branch of the Space Telescope Science Institute wishes to announce the availability of version 3.4 of the Space Telescope Science Data Analysis Software (STSDAS). Concurrent with the STSDAS release, we have also released v3.4 of the TABLES external package. Both of these packages are layered upon IRAF as external packages; it is therefore necessary to obtain and install IRAF (from http://iraf.noao.edu) before installing TABLES and STSDAS. STSDAS is linked against libraries in TABLES, so TABLES must be installed before STSDAS.

STSDAS includes some Python-based tasks; running these requires the STScI Python Libraries to be installed (all the non-Python tasks can be used in the traditional way and do not require Python or the STScI Python libraries). These tasks can only be run from PyRAF using standard IRAF CL task syntax, or within Python scripts using Python syntax.

The Astronomy Tools and Applications Branch of STScI also wishes to announce the availability of version 2.2 of STSCI_PYTHON. This release includes updated versions of Multidrizzle and CALSTIS as used by the HST ACS pipeline, along with new versions of aXe, numarray, PyFITS and PyRAF. A new task, saaclean, was also added for NICMOS data reduction. Use of the Python tasks requires upgrading to this version of STSCI_PYTHON.
