How can I generate a image from a text file?

Hi, there,

There are three columns in the text file. Two of them are position information, and another is magnitude of point source. Can I use IRAF generate a image with these information?

For example,
ra | decl | j_m
----------- +------------ --------
1.119851 | -89.91861 | 12.467
1.296576 | -89.933235 | 16.445
3.373635 | -89.964142 | 16.601
7.821089 | -89.912903 | 12.431
8.507479 | -89.971962 | 15.299
9.662913 | -89.924431 | 17.6
10.490366 | -89.969894 | 11.821
11.219777 | -89.901466 | 16.774
11.42433 | -89.934425 | 16.207
12.114551 | -89.900185 | 16.082

thanks

Hi Jay,

You may be able to use the ARTDATA package task MKOBJECTS for this, I say 'may' because the positions are expected to be coords and it's assumed to be a whitespace-delimited table so you may need to edit/process your example to get the proper input format. See the help page for details.

Cheers,
-Mike
