COS users.

Changes to the STIS Calibration Pipeline in HST MAST Archive
New STIS calibration software has been installed in the
HST MAST archive pipeline. The STIS team also delivered a
new dark correction table for data taken with the NUV-MAMA
detector which provides a better time and temperature
characterization for observations made after servicing
mission 4.

Updates to the COS/FUV Calibration
This article describes updates to three reference files which
improve the flux-calibration and flat-fielding of all COS/FUV
modes and significantly improve the wavelength solution of
the G140L/1280/FUVB mode. These reference files should
all be used simultaneously to calibrate COS/FUV data. Data
calibrated with the most up-to-date reference files can be
retrieved from the HST MAST archive at STScI.
