The spectrum of OH 471 /0642+44/

Abstract

Results of image-tube and Digicon spectroscopy of OH 471 (0642+44) are reported. Wavelengths of 89 stronger absorption features in the range 4000-6000 A are given, and a number of absorption redshift systems are suggested. The lack of radiation shortward of 4000 A is attributed to Lyman continuum absorption in the gas giving rise to the various absorption-line systems.
