Hi;
This is a question that concerns astronomers once in a while. I have
wondered what the limit is to the size of the arrays that IDL can create.
Some times IDL fails to read a FITS image complaining:
% Unable to allocate memory: to make array.
not enough core
This is not so uncommon if one has to deal with even moderate size cubes.
I have tried to use .SIZE to increase the default value for data area but
it doesn't seem to work. So the question is if there is a way to open a
very large image by IDL. IRAF seems to have no problem with this. Does
this problem arise from lack of RAM on the computer?
Any advice will be appreciated.
