Bad pixel determination?

["Creager, Robert S" <CreagRS@LOUISVILLE.STORTEK.COM>]

I was just starting work on some code to determine bad pixels, and was
wondering if anyone has done this or has comments?

I'm looking at the dark frames for V/I band, and they look very different
(this is data from Tom's Mark IV).  The following are histogram counts of
two dark frames.  From h4r1836.524, I'm sure I can call everything in the
last bin as bad (they are all 65535), and for h3r1836.524, the first and
last bin are bad (0 and 65535), but what about "31207 to 34328 =    2036",
or any others?  All those 2036 values are the same (32321 in this case, but
they change value from each dark).
