HST/WFC3: Recent Calibration and Machine Learning Updates for 2023

The Wide Field Camera 3 (WFC3) on board the Hubble Space Telescope (HST) has enabled high-resolution imaging and low-resolving power slitless grism spectroscopy from the ultraviolet (UV) into the near-infrared (NIR) since it was installed in 2009. The WFC3 team works to provide the latest, up-to-date software for calibrating and analyzing WFC3 images to ensure the highest quality data products possible for observers. This poster provides an overview of the available reference files for calibration (e.g. new UVIS post-flash files) as well as new notebook tutorials for WFC3 analysis and machine learning, which are hosted on our “WFC3Library” and “DeepWFC3” GitHub repositories. In the remainder of the poster, we discuss implementation of “stenv”, a software environment developed by Space Telescope Science Institute to replace Astroconda. Stenv provides a common environment for both the HST and the James Webb Space Telescope (JWST) pipelines. Here we will show how to get started with it and highlight the included packages.
