Jan,

ORGX and ORGY do _not_ correspond to the direct beam position for a
swung-out detector. Rather, the definition is that they define the pixel
of the detector which is closest to the crystal ("DETECTOR ORIGIN"). I
believe that this means that in your case they should _still_ be close
to 1024,1024 unless you also translated the detector.

IDXREF gives both the "DETECTOR ORIGIN" and the "DIRECT COORDINATES OF
DIRECT BEAM". So if you change ORGX and ORGY then make sure the latter
numbers get close to what you find with VIEW.

HTH,
Kay
