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 cataloged, 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_RA and KUV_DE: 
  KUV coordinate designation is composed of hours and minutes 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 G:
  The G (green) magnitude of the "three-image (UGR) method" used for 
  efficient detection of blue objects, e.g., by Haro & Herbig (1955), Iriarte 
  & Chavira (1957), Haro & Luyten *(1962), 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 Ocode:
  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 Ref:
  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.
