Description:
A listing of objects in the IRAS Point Source Catalog (1985) that were or
will be occulted by the Moon during 1991-2000 is presented. Objects from
the IRAS PSC that will have geocentric occultations during the years 1991-
2000 were identified using procedures described in Simon et al. (1986).
This list is a sequel to the list of occultations for the years 1986-1990
(ADC catalog 1123).

Note on IRAS:
If IRAS is blank, then record is a continuation for the star in the
previous record.
Note on q_flux*:
H = high-quality detection
M = medium-quality detection
U = upper bound
Note on cat, ID, rem:
For an object for which an identification with an object listed in some
other astronomical catalog is provided in the IRAS PSC, the catalog
number, following the conventions of the IRAS PSC, is given in the cat
field, and the object name in that catalog is given.
Where there is more than one identification with an object listed in
another astronomical catalog, an asterisk (*) appears in rem. In this
case, only the first identification is indicated in cat and ID. The rest
may be obtained from the original IRAS PSC.
