[BAA Comets] Submittings FITS images of 67P to the ESA/PSA archive

[Richard Miles]

Yes - Hi Erik,

I only really use Astrometrica to analyse fully-reduced images.l
For the initial calibration step, I use the preprocessing tools in AstroArt 
to batch process the FITS images (dark subtracts and flat-fields).

Astrometrica is pretty good at processing up to 25 frames in one go, and/or 
in tracking and stacking sets of FITS images.

Cheers,
Richard Miles
