Question about flatsStarted by:wierdling, 06/06/2009 10:31PM
Greetings all,

I am working with data from the ESO WFI,
and I have a question about flats. What
is the difference between a sky flat and
a screen flat? Is a screen flat the
same thing as a dome flat?

Thanks in advance :)

It should work very similar to the way
that the UNIX diff command works on
binary files.
