Perhaps it should also be noted here that the long crystal axis should be
oriented close to parallel to phi, in order to minimize overlaps. I have
heard anecdotal evidence (anyone else?) that this long axis, in plate
crystals, is usually normal to the surface of the plates.
Dear Francisco,
With a c axis of 650 Angs your phi-overlap problem is severe. When this
axis is close to being parallel to the beam, the angular distance in radians
between h,k,l and h,k,l+1 for a reflection hkl close to the top or bottom of
an image is the angle spanned by c* viewed at a
Hi Francisco,
you could try using these keywords in Mosflm:
POSTREF WIDTH 3
#since you have 0.1 degree oscillation and Mosflm can only handle 30
images at once, the default I believe is 5 images if I'm not mistaken
SEPARATION CLOSE
PROFILE RMSBG 25
POSTREF USEBEAM
Then I would start indexing
