The ISO-IRAS Faint Galaxy Survey

Finding Charts

IPAC OPTID Finding Charts and positional data are available for 387 IRAS FSS fields with 1 or more good ISOCAM source. Finding charts are in PostScript format. Each field is 4' x 4' scquare centered on the IRAS FSS position. The FSS 1, 3 and 10 error ellipses are marked along with the ISOCAM position (concentric circles). Stellar objects are indicated as filled circles (occasionally as ellipses when double stars are unresolved) and galaxies as open ellipses. Relative brightness is indicated by size of the circle/ellipse. Object classification is poor at the fainter magnitudes and compact infrared galaxies at m > 19 are frequently classified as stellar.

The image below is the field of the z = 0.278 Luminous Infrared Galaxy associated with F14491+6040 (Levine et al. 1998, Smith et al. 2000) shown in the images above. The concentric circles mark the position of the ISOCAM source; objects numbered 1-6 (1 is unreadable in this frame) correspond to the first six objects in the text file, listed, in part, below the image. These are ordered by the likelihood of being the optical object associated with the IRAS source assuming the classification applied by the measuring engine. In this case the open ellipse coincident with the ISOCAM source (object #1) is shown to be a galaxy pair on the Digitized Sky Survey image and there is clear evidence for tidal interaction on the deeper G and I-band ccd images from Lick Observatory.
