9.4 STSDAS, STSCI_PYTHON and Astropy

STSCI/IRAF has been deprecated as described in the 2018 STScI Newsletter. To ease this transition for long-time IRAF users, a number of IRAF routines have been ported to python and documented via a set of Jupyter Notebook Tutorials, located in a Central Repository. The WFC3 team continues to develop tools aimed at the user community. New tools will continue to be added. We note that many of the software tools that are useful for analyzing HST data can now be found in the Astropy (the current community-supported Python Astronomy package) library of python modules.
