   These OGLE-II variables have been released with actual photometric
measurements (several tens to a few hundreds data points, depending on
the object), as in Hipparcos variables.  So they can be categorized into
"certain" and "suspected" variables as were done in the past for Hipparcos
variables.  The single problem could be the time required to examine
the actual data...  If one can examine the light curve (and identifications
etc.) at a rate of 1 star/min, 200000+ star would require more than
600 working days if one spends five hours/day on them...

   So,

   would sound very realistic.  One may publish IBVS article entitled:

   "Analysis, suggested classifications, cross identifications for OGLE II
variable star candidates 1. -- BUL-SC1 1 to 100"

   A batch of similar articles would surely reduce the load for the GCVS
team to examine the real data!
