The observations described in
Sections IV.A.8 show that a
correction of as much as 20% should be applied to the photometry
in the 100 µm band because of the photon-induced responsivity
enhancement caused by passage over the Galactic plane.This correction
depends on the detailed history of the individual scans which
go into making up a source. The correction scheme described in
Section VI.B.4
is only valid in a statistical sense and is based
on guess-work for those areas which were not covered by ascending
and descending. It should be emphasized that these corrections
were not incorporated into the instrumental fluxes recorded in
the WSDB.
No correction has been attempted for the extended emission
maps.
