This data set consists of "Skyplate Images HCON(Hours-CONfirmed)-3" on 5x5 in. black and white negatives. The IRAS observations were made by the confirmation process that consisted of examining multiple observations and identifying which plausibly belonged to the same object. HCON-1 represents the first hours confirmed data observed with time separations from 100 min up to 36 h. HCON-2 represents the data confirmed about 2 weeks after the first hours confirmation, and the HCON-3 data were confirmed after the second confirmation. Generally, the hours-confirmation was run on groups of successive satellite operation plans. Each skyplate image covers 16.5x16.5 deg on the celestial sphere, with a pixel size of 2 arcmin and an angular resolution of 4-6 arc-min. For more information on this data set, see "IRAS Catalogs and Atlases Explanatory Supplement," edited by C. Beichman et al., 1985.
