task to create a fits image?Started by:Arp, 01/21/2010 04:15PM
Hello,

Is there a task which does the oposite
to LISTPIX? e.g. I provide an ascii
file, containing xy coordinates and the
pixelvalue for this coordinate, and the
task generates a fits file out of it. Is
there something which can do this?
thx.

Hi,

The task irlincor is declared like
this in noao$imred/irred/irred.cl:

task irlincor = "irred$x_irred.x"

While this works OK under the cl, it
fails under PyRAF.

As far as I can see, this is the only
example in the whole IRAF tree of a task
