DIRBE BEAM OFFSETS: Cryogenic Mission
Version:  Pass 3B data release, April 1997
 
This file tabulates Beam Centroids and Solid Angles for all 16 DIRBE
detectors for the duration of the Cryogenic Mission (11-Dec-1989 to
21-Sep-1990).  Centroids are expressed as (in-scan, cross-scan) offsets
from the origin (0,0) defined by the attitude solution.
Note that the centroids for bands 1-4 are time dependent.
See the COBE/DIRBE Explanatory Supplement and BEAM_PROFILE
data product for further explanation of beam coordinates and normalization
of the beam profile.  See the description of the CIO data product in
Chapter 5 of the Explanatory Supplement for an explanation of how to
use these offsets in the construction of resolution 15 coordinates.
