Can IRAF process 2MASS data?Started by:jay, 05/22/2007 08:07AM
Recently, I try to use IRAF to process
the 2MASS data. The data format is
binary, namely, it is .bin.

And I try transform .bin data into IRAF
image format, but it doesn't work.
Can IRAF process this kind of data? And
how?

It is very important to me....
