Re: new stars and such

[Arne Henden <aah@nofs.navy.mil>]

Michael,
   The IBVS, over the last few years, has been leaning towards
fewer papers covering more stars.  Since both objects are from
TASS, I'd put them together unless you do extensive modelling of
one system or another.
   ASAS is not the be-all/end-all.  Greg's photometry does not go that
deep and is only V-band at present, covers only the southern sky,
only has been released for RA 0-6hrs, etc.  They also do not do a
good job on sub-day periods unless the period is already known.
Tom's multiple-scan data is just as useful IMHO.  That is not to
say that Greg's work should be ignored; just the opposite.  He has
presented data on the southern sky, ignored by surveys.  TASS can
and should do better, especially on the fainter stars.
   Regarding new objects:  my usual targeting method is to look
for unusual objects rather than just another vanilla RR Lyr or
EB.  These tend to be more fun to look at, and in addition, easier
to publish.  You need to think about what you want to observe and
what limits might be placed due to your hardware.  Do you want
short period stars only?  Pulsating/EB/irregular?  How faint can
you go with good signal/noise and good time resolution?  I always
think that you should find a doable project where you can get at
least 0.01mag precision, filtered, at a reasonable time resolution.
This might mean a fainter but longer period star, or a rapidly
varying bright system, but equally important is that the system
has to be something you are interested in.  I personally have
lots of objects that need to be followed up and can give some
guidance, but you might find a TASS/TOM object that also interests you.
