For convenience in studying Galactic phenomena, the sky survey data
(three sky coverages) within 10° of the Galactic plane were
reprojected from the 16.5° x 16.5°
Sky Flux Plates into Galactic coordinates.
An equal-area cylindrical projection
was used. Each coverage is represented as a set of twenty-four
16.7° x 20° fields (499 x 599 pixels stored in FITS format)
with field centers at integral multiples of 15° Galactic
longitude. The 2' x 2' pixel size is the same as that of the
Sky Flux Plates, however the remapping
resulted in a slight degradation in resolution relative to the
original 4' - 6'. For more information, see the Explanatory Supplement.
The Galactic Plane Maps have been superseded by the ISSA Galactic Plane Mosaics. The processing for the ISSA images included a superior destriping algorithm as well as subtraction of a model for the zodiacal intensity. Note: A special high-resolution set of maps for the 60 and 100 micron bands only has recently been released. The maps, which have angular resolution ~1', cover the Galactic latitude range |b| < 4.7° and selected regions at higher latitudes. IPAC offers an on-line interface for extracting images from this High Resolution IRAS Galaxy Atlas (IGA). The complete IGA, not yet available on-line here, may be ordered on tape or CD-R. Contact the Coordinated Request User Support Office (CRUSO) for more information. Depending on the affiliation of the requestor, a fee may be charged.
