This data set consists of maps that indicate the approximate position of the OSO 8 spin axis during the lifetime of the mission with respect to selected X-ray sources, displayed on a local coordinate system (i.e., sky map). The right ascension and declination of the marked central position in each map are shown at the bottom. Sources are indicated by abbreviations, as listed in the accompanying catalog. Sources relevant to both the positive-spin-axis-pointing detector of experiment 75-057A-06 and the negative-axis-pointing detectors are shown on the same map. Starred sources refer to the negative-spin-axis direction. The right ascension and declination of the marked position relate to the starred sources. The catalog was compiled before the OSO 8 launch, so most of the candidate sources are now known to have fluxes that are undetectable by experiment 75-057A-06. Other sources, although detectable, have by now improved positions. However, with the maps and the catalog, one should be able to find the approximate coordinates of any point on the maps. Catalog source positions are given in 1975 epoch coordinates. Day numbers along the spin axis path are indicated, with day 0 corresponding to January 1, 1975.
