Subject: [vsnet-chat 5144] Re: [vsnet-id 599] Re: GCVS errors for CVs
In the case of the recent positions that Mike Simonsen supplied,
I went through and compared with current 'best' astrometric catalogues
to get positions. I verified several cases using source charts from
the discovery papers. I then looked in SIMBAD to see which variables were
shown with approximate coordinates (there were several). Since most of
the stars mentioned were fairly bright, they already had precise positions
in SIMBAD from Tycho-1. For the others, I then sent a note to Gerard
Jasniewicz (who takes care of such things in SIMBAD), and he has already
corrected the positions for the relevant stars in database. There was
also an error in SIMBAD itself that was taken care of at the same time.
Following on the posts from yesterday, Berto Monard pointed out
another SIMBAD error (a CV star given as a galaxy in SIMBAD). This too
is already fixed.
>> I hope Taichi Kato's GCVS2000.....
The current Moscow GCVS version is from December 2001. My concern,
frankly, is not with correcting the GCVS---as Kato-san points out, they
rightly keep their own counsel on such matters. Instead, I worry about
improving SIMBAD, which is much more likely to be the first stop for any
researcher looking up specific variable stars. It is also updated daily
with additions, corrections, and new bibliographic references.
