Description:
    The catalog is a list of 1186 ultraviolet-excess objects found during
    two surveys with the Kiso Schmidt telescope of the Tokyo Astronomical
    Observatory. The UGR three-image method was used to detect the objects
    catalogued, which range in blue magnitude from about 10.0 to 18.5. The
    table contains equatorial positions to an accuracy of about 0.5
    seconds of arc (equinox and equator B1950.0, epoch of observation),
    magnitudes (green of the "three-image [UGR] method"), color indices
    (as estimated from the enhancement of the U image relative to the G),
    object codes (white dwarf, QSO, diffuse object, etc.), and alternate
    designations (in addition to a KUV coordinate designation).

Note on KUV:
    KUV coordinate designation is composed of hours, minutes and tenths of
    right ascension, sign, and degrees and minutes of arc of declination.
    Note that this coordinate designation does not follow the standard IAU
    convention because the coordinates are rounded and not truncated.
Note on KISO-a and KISO-n:
    Another designation consisting of a Kiso area number (see Kiso
    Information Bulletin No. 1, 1979) and a serial number within the area.
Note on Gmag:
    The G (green) magnitude of the "three-image (UGR) method" used for
    efficient detection of blue objects, e.g., by Haro & Herbig (1955,
    Bol. Obs. Tonantzintla y Tacubaya No. 14, 8), Iriarte & Chavira (1957,
    Bol. Obs. Tonantzintla y Tacubaya No. 16, 3), Haro & Luyten (1962,
    Bol. Obs. Tonantzintla y Tacubaya No. 16, 3), and others. See the
    source reference for additional details.
    A colon (:) in byte 54 denotes an uncertain value.
Note on CI:
    Estimated as the enhancement in the U image relative to the G,
    calibrated with known values of U-B color. A colon (:) in byte 59
    denotes an uncertain value.
Note on Oclass:
  A letter object code to denote the following characteristics:
    W   spectroscopically confirmed white dwarf
    Q   quasar
    D   diffuse object with possible accompanying halo
    V   variable that is definitely brighter or fainter on print of the
         Palomar Observatory Sky Survey than on the Kiso plate
Note on AName:
    An alternate object designation in a previous catalog, composed of a
    reference number in bytes 63-64, followed by the designation in the
    cited catalog.


Remarks and Modifications:
  A magnetic tape containing the first and second Kiso Surveys in separate
  files was received from Dr. M. Kondo on March 11, 1985. The following
  modifications were made to produce the current catalog:
  1. The two lists were moved to online storage and merged
  2. Minus signs on negative declinations were moved to always occur in the
     same byte. Zero declinations had lost their signs; these were added by
     using the respective KUV designations. Plus signs were then added to all
     positive declinations.
  3. Uncertainty codes for G magnitude were moved to byte 54 so that they do
     not occur within the magnitude field.
  4. The combined list was sorted by increasing right ascension.
