Hello,

I'm doing some profile-fitting
photometry on a bunch of images and we

.coo file corresponding to each file. I
wrote a program that calculates a
predicted pixel position based upon an
offset from one image...

Hi,

When running geomap to calculate the
transformation from one image frame to
another, the x and y pixel shifts are
reported to 7 decimal places, enough
precision for any need. But the
rotations in degrees are reported to
just three decimal places. ...

Hi All

It may sound a stupid Q, but how would
you call DS9 from the loginuser.cl. I
would like to skip the step where I have
to start DS9, and run it in the bg,
before every IRAF session. I am not that
familiar with coding in c-shell.

Thanx

Journaling in IRAF?Started by:baryonicminority, 06/29/2006 09:03PM
Hi all,

I was wondering if IRAF has a journaling
function that records sessions, similar
to the one that IDL has.

Any help or advice would be much
appreciated.
