Scanplot
Syntax: block xa xb xc.
Default: block 0.2 0.2 0.2.
Sets the size of the crystal in millimeters. The orientation
of the crystal can be specief with orient.
If volume is on the
size of the crystal and the diameter of the
collimator are used in the calculation of
the diffracting volume.
Use sphere to set a spherical crystal.
Syntax: capillary state
Default: capillary off.
Plots the angle between capillary and primary beam as a function
of crystal rotation.
capillary on implies

Syntax: clearimpact.
Only applicable if impact data are defined.
Clearimpact clears the array with impacts on the detector. After a
new go command a list of actual impacts on the
detector is created. With each succeeding go or
plot command, these reflections will be displayed.
Use clearimpact to remove this list of
actual impacts. Note the list of impacts (defined with
impact) is not removed (you have to use
noimpact to clear that list).
