Note that there are very good charts of EBs created in
B.R.N.O. available through

http://astro.sci.muni.cz/mapky/brno/

Identifications of spurious cases are based on surveys by
Jan Manek at Sonneberg observatory and/or visually observed
minima and/or finding charts from discovery literature.

Famous example is V728 Her. GCVS position for this star
points almost exactly to GSC 3081 0571, but the real
variable is about one mag. brighter GSC 3081 0676 as shown
on the B.R.N.O. chart. This is confirmed by CCD observations
of some guys from around here.

Best regards,

Ondrej Pejcha

P.S: The list of Mike Simonsen contains one error:
GSC number of FL Ori is identical to that of SS Cet. GSC
number of real FL Ori (B.R.N.O. chart) is 4755 1282.
