I would like to thank Elena Kazarovets and Kolya Samus for their detailed
examination of the identification problem for V1485 Cyg and what we now know
are related NSV names. It was of course not my intention to make their work
more complicated. However, it looks as though I got things both wrong and
right on this one:
>> In IBVS No. 4675 (1999), B. Skiff published for these star accurate
>> coordinates (19:38:08.1 +29deg40'43", 2000) and identifications with
>> CSV 4759...
>> In 2000, V.P. Goranskij, a GCVS team member, measured an accurate
>> position for V1485 Cyg, found to be 19:38:08.660 +29deg40'53".70 ...
>> ...He thus considered Skiff's findings wrong....
I have retraced my steps on this and agree that my IBVS position is
for the wrong star, and also see how I made the error. The variable is not
present in USNO-A2.0, and I mistakenly chose a nearby star without further
assessment. Luckily, I've learned a few things about the catalogue business
since 1999.
>> B. Skiff now suggests still another NSV identification for V1485 Cyg, with
>> NSV 12235 (actually there is no conflict in variability type; ea in the
>> NSV catalog is in the "Spectral type" column and stands for Halpha in
>> emission).
Yes, I misread the VizieR output table; sorry for the confusion.
Too bad there are no Greek-letter fonts (viz. e-alpha) in the VizieR reports;
The NSV suggestion seems to be correct at least!
>> Summarizing: we now decide to identify, for GCVS purposes, V1485 Cyg,
>> NSV 12235, and NSV 12238. The only star revealing a very red color is
>> Goranskij's candidate for V1485 Cyg. Its GSC 2.2 position (19:38:08.664
>> +29deg40'53".71, 2000.0) is in EXCELLENT agreement with Goranskij's
>> astrometry.
