[daip] question on fluxing

[John Keck]

Hello,

I'm trying to integrate the flux density in a very irregularly shaped
region of several maps.  I was looking for a task that would add the
values of all the pixels in a map that rose above a given threshold, but
was unable to find anything.

I was thinking that I could write an external program to do the job, but I
couldn't find a way to save the flux values of a map to an external file
(I'm running under Solaris).  How can I do this?

Thank you,

John Keck
