ccmap/xy2sky problemsStarted by:jtg0819, 02/22/2011 06:42PM
I am doing photometry on 90-300 stars
per frame. My intent was to use the
ccmap/xy2sky packages to create a
coordinate list of these stars and then
use those coordinates to match my stars
to themselves in the USNO database.
After painstakingly creating ...

ccmap doesn't create solution fileStarted by:jacob, 12/13/2008 06:18AM
I am using ccmap and cctran to do
astrometry. However, after creating the
database file with ccmap, cctran always
returns the output equal to the input.

I believe this is because ccmap just
won't create a solution file. However,
a results file and a ...

Hi Mike,

A PyRAF user found something which the
CL allows but PyRAF does not. In
checking it, I realized it looks like it
may be a bug which you may wish to fix.

In ccdproc.cl, there are two calls to
_ccdtool().

In both of them, the "nointerp"...
