I tried installing "finder" manually as
an external package in V2.16. After
some fiddling I got it to load okay, but
when I go to run it I get the following:

images. The images are in one directory
and are called in bash by a "for file in

The cosmicrays task is throwing

2.15.x. Had to go back to 2.14.1 before
it worked. I'm running a 64-bit Ubuntu

I am experiencing a strange problem: I

Hi,
I'm reducing GMOS data. The mask has 25
slits and I have 8 exposures of the

(gsreduce, gstransform, gsskysub,
gsextract, gscalibrate) I realized that
the wavelength calibration for the
spectrum number 17 was not good....
