The IRTS data coverage is represented as color overlays (footprints) in the all-sky image above, to indicate where IRTS made its observations. This all-sky image is made from the IRAS Sky Survey Atlas (ISSA) data; the footprints (positions) of IRTS image fits files using the FILM and FIRP instruments are indicated as red rectagles; point source positions from NIRS are shown as yellow dots, and positions of sources with spectral information from MIRS are shown as cyan dots. There are 1067 fits images from FILM and FIRP, they are approximately 8 X 8 degrees, and lie along the strip indicated in the red pattern on the all-sky map. The 14294 point sources and 536 spectral sources fall on a narrower strip of ~4 degrees, within the same regions of the sky as the image data.
The canonical paper for IRTS is Murakami et al. (1994).
