Hello all!

I'm trying to reduce my first set of 5 images using Charon. They are .st8
formatted, corresponding to Phocaea (25) on 01/20/00. This was inside ACR
regionC zone, so I decided to take a look at him, in order to estimate the
incidence of my instrumental errors upon the astrometric accuracy of the
derived position.

Before running on my image, and following the manual recommendations, I've
performed the reduction of d:\image\ngc4565.st6, with no problems. Also
I've run charon without any parameter in order to see the setting
available. Observatory code, focal lenght, etc have been set properly.

As a first test run, and before trying to use ACR catalogue, I'm chose
the default reference one (which I guess it's GSC1.1). Therefore, my
command line is:

c:\Archivos de programa\GUIDE7> charon pp.st8 -oa25

and here's what CHARON complains in CHARON.LOG file:

CHARON version Dec 30 1999 19:55:43
Observing from MPC station Fabra Observatory, Barcelona

Latitude set to 41.4167, longitude to 2.1258
Image identified as .st8 file
pp.st8 not opened

So it seems that CHARON is able to recognize the format but not open the
image. I'm sure the image is not corrupt because I can display it with
CCDOPS.

Does anybody have had such a similar problem?

Thanks in advance,
