Abstract
New observations of the spectrum of Pt/Cr-Ne hollow cathode lamps have been made to provide accurate wavelengths for more than 5000 chromium lines for wavelength calibration of the Space Telescope Imaging Spectrograph. New infrared spectra of chromium hollow cathode lamps will be taken to produce a comprehensive line list for Cr II extending from 1130°A to 5.5 ìm and to increase the accuracy of the Cr II energy level values. Lines of Cr II are prominent in the spectra of many astrophysical objects, especially in chemically peculiar stars, and our results will be significant in interpreting these data.Proceedings Title
