Recent Calibration Efforts and Performance Updates for HST/STIS
Abstract
The Space Telescope Imaging Spectrograph (STIS) continues to enable the astronomical community to carry out innovative UV and optical spectroscopic and imaging studies with its unique observing modes, over two decades after its deployment on the Hubble Space Telescope (HST). In particular, STIS allows spectroscopy in the FUV and NUV, including high spectral resolution echelle modes, imaging in the FUV, optical spectroscopy, coronagraphy, and long-slit spatial scanning on the CCD. We present work on a new Python-based defringing tool for STIS CCD observations, updates to the STIS Data and Instrument Handbooks, the status of the NUV-MAMA dark current, and a discussion on the impact of observatory/gyro jitter on spectroscopic observations. Additionally, we discuss efforts to improve the relative flux calibration of the NUV echelle modes and an update on the STIS instrument focus.
