Abstract:
We have identified, using Palomar Observatory Sky Survey (POSS) prints, the optical counterparts of six of the seven sources from the Equatorial Infrared Catalogue Number 1 (EIC-1) previously identified by Sweeney et al. (1978) with only AFGL infrared sources. We have estimated their P and R magnitudes from a measurement of the diameters of their images on the O and E POSS prints. The source EIC 725 does not appear to have an optical counterpart.
