Constructor.

arguments:

cell

The cell to which the reflections belong

p

The position of the goniostat and the detector at the beginning of the scan.

hkl

The DataSet() object containing the reflections to be predicted.

optional arguments:

durationmax

the upper limit for the reflection duration factor to accept a reflection. If set to 0, the duration is not limited.

detectorsizemargin

the insensitive edge of the detector.

clockwise

whether the angle of interest turns clockwise.

cmat ( self )

Return the hkl2c matrix at the starting position p

hitrot ( self )

See where the reflection is reflecting during the scan

This routine checks whether refls actually hit the detector

mm ( self )

Calculate left and right impact vectors on the detector

returns 4-tuple of vectors mmx1,mmy1,mmx2,mmy2

rot ( self )

See where the reflection is reflecting during the scan.

This routines does not check whether it actually hits the detector

simrange ( self,  anglim )

Simulate a rotation of anglim radians starting from p

Return an array representing the number of intersections for each reflection.
