Michael,

First, i have no excuse - the positions i have were right, but some 
parameters were wrong and the program got some nearby stars. I feel very 
embarassed.

We do have all the files, and i will rerun the reduction with the 
correct parameters and compare the results to spot other possible 
errors (there are about 400 different fields to be checked).

As always, thanks for your patience and for spotting these ;-).
