These are still not use cases that anyone would encounter. Testing a toaster to find out if it makes coffee or not isnt
relevent. This is the same..
I created that feature so that I could extensively test various options in the plate-solvers. I then realized that others might be
able to use it for checking software setup, so I made it available. I didn't mention this aspect because you specifically asked for
a customer use case.

A third use case is for comparing the accuracy of the various plate solvers. I can create images from any part of the sky, at any
image scale and pixel dimensions, and with any rotation. I then feed these images to the various plate solvers to measure their
accuracy.

So there you go... three use cases. All are quite useful, despite what you think. :-)

Good work sir.

relevent. This is the same..

Right, but ASTAP is under active development. As was pointed out earlier in this thread, there have
been fixes
even since I used it last. It's possible that if the problem is there (and we still don't know that, it could
be SGP), that
it's already been fixed.



Is it correct that the latest version is a *beta* version? (v0.9.421) It is free now, but will it be free when it is
released as v1.0?

I just downloaded it, installed it and the G17 database. I then used APPM's NASA SkyView camera type to
get an emulated image, which solved in PinPoint in a few seconds. Trying to solve the same image in ASTAP fails
despite that it seemed to extra the correct RA/Dec and image scale from the FITS header.

Any idea of what I should check? Or is this a possible bug in the application?


Ok, so I ran these myself and they solved in 0.2 and 0.3 seconds with the G18 database. It seems that however
these images were generated, they were generated with a small enough FoV that they didn't include enough stars
that were in the G17 database.
