โœฆ Synopsis

On scans obtained with the Oxford photoelectric spectrometer, the [CalI] transition 4s 2S1/2-3d 2Da/~ is identified with a weak Fraunhofer line. It is argued that the strength of the line is consistent with the abundance of calcium which is derived from the permitted lines of CaI and Can.

Divergence between determinations of the iron abundance from permitted Fe lines and forbidden FeII lines is discussed and a re-examination of the equivalent widths of two of the [Fen] lines is proposed.
