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…
A Definitive Determination of the Interstellar Carbon Abundance toward rho Ophiuchi A and B
Adam M. Ritchey, S. R. Federman, Daniel E. Welty +1
We present the results of an effort to derive interstellar gas-phase C II abundances along the lines of sight toward rho Oph A and B. Our analysis is based on high-resolution NUV a…
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…
Updated Sensitivities of the Five STIS L-mode Gratings
Amy M. Jones, Svea Hernandez, Joleen K. Carlberg +1
Re-derivation of the sensitivities of all of the Space Telescope Imaging Spectrograph (STIS) observing modes were required after major updates were introduced to the model atmosphe…
The UV Legacy Library of Young Stars as Essential Standards (ULLYSES) Large Director's Discretionary Program with Hubble. I. Goals, Design, and Initial Results
Julia Roman-Duval, William J. Fischer, Alexander W. Fullerton +44
Specifically selected to leverage the unique ultraviolet capabilities of the Hubble Space Telescope, the Hubble Ultraviolet Legacy Library of Young Stars as Essential Standards (UL…
