ADC_Keywords: Infrared sources; Occultations

Description:
   The Lunar Occultations of IRAS Point Sources lists objects in the IRAS
   Point Source Catalog that were occulted by the Moon during 1986-1990.

Introduction:
   The occultation predictions were based on the formulae for the lunar
   ephemeris developed by Van Flandern and Pulkinnen (1979).  The
   topocentric predictions from this code are accurate to about +/-30s.

Note on yr*:
   yr1 and yr2 are the starting and ending years of the interval during which
        geometric events occur for the object. Some of the objects for which
        the ending year indicated is 1990 may actually have events in
        subsequent years because times later than 1990 were not considered in
        the present work. For objects having two intervals during 1986-1990
        in which geometric events occur, the second interval is indicated in
        the line following the first entry.
Note on flux*:
   flux fields list the mantissa of the 12, 25, 60 and 100 um flux densities, 
        in Janskys, as given in the IRAS Point Source Catalog.
Note on exp*:
   exp fields list the exponent of the 12, 25, 60 and 100 um flux densities,
        in Janskys, as given in the IRAS Point Source Catalog.
Note on q_flux*:
   q_flux fields refer to the flux-quality flags at 12, 25, 60 and 100 um, 
        as indicated in the IRAS Point Source Catalog:
   H    =       high-quality detection
   M    =       medium-quality detection
   U    =       upper bound
Note on cat:
   For an object for which an identification with an object listed in some 
        other astronomical catalog is provided in the IRAS Point Source 
        Catalog, the catalog number, following the conventions of the IRAS 
        Point Source Catalog, is given.
Note on name: 
   For an object for which an identification with an object listed in some 
        other astronomical catalog is provided in the IRAS Point Source 
        Catalog, the first object name, following the conventions of the IRAS 
        Point Source Catalog, is given.
Note on rem:
   An asterisk appears where there is more than one identification with an 
        object listed in another astronomical catalog. Only the first is 
        indicated in cat and name. The rest may be obtained from the original
        catalog.
