Galactic Plane Maps
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'.

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.
