Wavelength Calibration Accuracy Across the STIS CCD: Pipeline Update and User Guidance
Matilde Mingozzi, Robert Jedrzejewski, Matthew Siebert +3
We investigate the wavelength calibration accuracy of STIS CCD spectra as a function of detector position, focusing on the E1/E2 pseudo-apertures. Comparison between measured lamp…
Barycentric Corrections for HST/STIS Data
Joshua D. Lothringer, Joleen K. Carlberg, Sean Lockwood
We describe $\texttt{stistools.barycentric_correction}$, a new Python utility for calculating barycentric timing corrections for HST/STIS observations. This tool replaces the depre…
The Hubble Advanced Spectral Product (HASP) Program
John Debes, Ravi Sankrit, Travis Fischer +39
The Hubble Advanced Spectral Products (HASP) program is designed to robustly coadd Cosmic Origins Spectrograph (COS) and Space Telescope Imaging Spectrograph (STIS) spectra within…
Overview of the New Hubble Spectroscopic Legacy Archive
Ravi Sankrit, John Debes, Matthew Burger +34
The new Hubble Spectroscopic Legacy Archive (HSLA) provides coadded spectra of individual targets that have been observed with the Cosmic Origins Spectrograph (COS) and the Space T…
Recalibration of Pre-SM4 STIS Echelle Throughputs
Matthew R. Siebert, Joleen K. Carlberg, Svea Hernandez +1
Recent improvements to stellar atmospheric models have merited updated flux calibration for high priority STIS observing modes. Specifically, in the FUV and NUV, continuum differen…
Updating the Sensitivity Curves of the STIS Echelles (Post-SM4)
Svea Hernandez, TalaWanda Monroe, Joleen K. Carlberg
The STIS team re-derived on-orbit sensitivity curves for the echelle modes for post-servicing mission 4 observations using the standard DA white dwarf G 191-B2B. These new updates…
