ESO webpage ... BLAH

So!! The whole day checking for possible sources of error that would cause the mag difference ... nothing.

A the end, desperate measure, a rough calibration using the stars they send you in a table gives a zero point difference ... exactly the difference I'm getting between FORS and ACS photometry ...

The question is ... why ESO has wrong zero points in their webpage??? WHY???

Tomorrow I'll come back to that and do that "properly".
