Re: Yet Another Survey Paper: PSST

[droege@snapmail.us]

I always look for the figure 3 equivalent in this paper.  It shows that
PSST is a factor of about 8 less noisy than TASS.  Sigh!  Part of this is
our location, part is that we jump all over the sky.

I still think that moving around the sky is a better way to get at the
true accuracy of the data.

A survey like PSST will probably only sit on a field a few times.  My tass
schedule gets hundreds of epochs per year.  We should thus do better at
characterizing long period variables.  We shall see.  One survey cannot be
optimized for everything.  Looks like we will do best for red long period
variables.  We now have 2 years in the can.  If I can keep it up for 3
more, then it should be a nice set of data.
