astrometric calibration error

[Milica Andjelic]

I want to know what are errors of my astrometric calibration done at astrometry.net?

Is it written in some output file?

Hi,

No, we don't report any useful stats on the accurate of the solution... one thing you can try is to look in the ".corr" file, which lists "correspondences" -- stars that we think we matched between your image and the reference catalog.  It lists the X,Y pixel positions and RA,DEC positions of "index" (reference) and "field" (your image) stars, along with a confidence score for each match.  If you looked at the average distance between those matches, that would give you a reasonable estimate for the error.

cheers,

dustin
