In my old setup at Stanford (linux iraf;
version 6 ds9), I could get nice
positions within an image by loading the
image into ds9 using the display task
(say after setting stdimage=imt800) and
putting the cursor onto a location and
reading off the posit...

Hi there,

I am not using this for any true kind
of publication but more so we can
reference material. However, it is very
important that I have a coordinate
system where I can plot the WCS.
Whenever I try to save as a PNG or JPEG
it does not functio...

Double slashes cancel out in Iraf pathStarted by:ncaon, 09/26/2008 04:24PM
Hi,

I've just noticed that when a string
used as a path contains two adjacent
slashes, they cancel out. The following
example will make it clear:

[code:1:92230909ba]
ecl> s1="/1/2/3/4/"
ecl> path(s1)

double precision images in 2.15Started by:duvall, 01/12/2011 04:47PM
I have a fits image in double precision
with bitpix=-64 that the new iraf 2.15
sees as all zeroes. Iraf 2.14 sees the
data fine. An image with this property
is available at
