Note (1): For empty fields the IRAS position is given in brackets. Note (2): Spectral class and magnitude of the star is taken from SAO or The Bright Star Catalogues. For the few uncatalogued stars, B magnitude is estimated from the diffraction spike length on the plate. Note (3): Not color corrected. Note (4): 'L' denotes values that are upper limits only, ':' denotes moderate quality fluxes. Note (5): Ratios are given for those galaxies with better than upper limit detections at both 60 and 100microns, and that have COSMOS B-magnitudes. Note (6): For abbreviations, see paper p569.

Note (1): COSMOS positions are measured from UKST plates (see paper p113L). For some objects on the edges of plates, catalogue positions are given. For empty fields the IRAS Point Source Cat. position is given. Note (2): 'L' denotes values that are upper limits only, ':' denotes moderate quality fluxes.
