   Thanks!  The present list seems to be very appreciated, and agrees well
with my own "eye" examination (since I only record remarkable idenfications,
I don't have a complete list yet).  I did similar automatic search for RXS
sources against all GCVS stars, and found several noteworthy identifications,
but the severe coordinate problem GCVS I encountered indeed became a motive
force for GCVS revision program using USNO.

   Some of the listed object probably look better fit other normal stars.
For example at the location of 1RXS-F J185334.3+291138 (for HR Lyr), there
is a relatively bright candidate star GSC 2121.1881.  Eye examinations
can have an advantage in examining such "noisy" (in terms of CV/normal star
ratio and the error circle) catalogs.
