  1. HRC-S/LETG: Degap and Wavelength CORRECTIONS Vinay Kashyap Sun-Mi Chung Pete Ratzlaff Jeremy Drake CXC/SAO

  2. AR Lac trace (RAWX,RAWY) (DETX,DETY)

  3. rms = 0.014 Å (0.010 Å)

  4. rms = 0.010 Å (0.006 Å)

  5. HRC-S Degap Corrections $CALDB/data/chandra/hrc/bcf/gaplookup/hrciD1999-07-22gaplookupN0002.fits – based on detailed corrections to line locations as a function of detector positions previously computed from polynomial degap solutions – replaces Pete Ratzlaff’s corrlam script – improves wavelength scale; rms ~ 0.006 Ang over S1 – has no measurable effect on continuum spectra – next (and final) step: apply to empirical degapping corrections derived from continuum spectra
