Correcting things ...
No posts the last days because monday was a holiday and tuesday, yesterday and most of today fixing the whole catalogue for a cluster because FORS WCS is not precise in geometry. Yes, don't trust it, it's terrible and gets worst in the borders of the image ... blah. Now things match and are fine!Lesson learned. First correct WCS (by default, even if you think it's OK) and then reduce the data!!
Now digging the old photometry, already done, for another cluster!

Ah yes, astrometry is the worst! When we get astrometry.net close to solving individual cameras for their individual, repeatable distortions, I will be sure to let you know. I dream of a world in which no-one has to suffer under incorrect WCS!
Astrometry.net will be a great thing to all astronomers! Hope it gets "flying" soon!!! Let me know when it can be used!!
Incorrect WCS is really a pain!! :-))
