I found a few CCD comparison stars for TT Ari:
This one is from ASAS-3:
RA: 02:07:14.2 Dec: 15:19:48.3 V:11.829 Verr: 0.039
Arne's .dat file is faint. These are the brightest stars I could fine.
Try to stay within 3 mags of TT Ari. So use the 14.6 star first and
switch to 15.2 if TT Ari gets fainter than 12.2.
RA: 02 06 49.0 Decl.: +15 17 00.1 V: 14.624 Verr: 0.017 B:
15.300 Berr: 0.040
RA: 02 06 49.8 Decl.: +15 20 05.5 V: 15.210 Verr: 0.042 B:
16.039 Berr: 0.065
I'm doing this from my laptop in a hotel room, without my usual tools.
So I'd appreciate it if someone else would double check these values.
