Abstract
ABSTRACT Spectrophotometry of the QSO NRAO 530 with the KPNO Cryogenic Camera is reported. A redshift of 0.902 is determined from the H-beta, H-gamma, and 3727 A forbidden O II emission lines, confirming a redshift that had been based on a single line, the 2798 A Mg II. The H-beta equivalent is smaller than in normal QSOs, which may be characteristic of optically variable QSOs.
