_diffrn_scan_axis.reference_angle

Name:
_diffrn_scan_axis.reference_angle

Definition:

   
     The setting of the specified axis in degrees
     against which measurements of the reference beam center
     and reference detector distance should be made.
     In general, this will agree with
     _diffrn_scan_frame_axis.reference_angle.
     If the individual frame values vary, then the value of
     _diffrn_scan_axis.reference_angle will be
     representative of the ensemble of values of
     _diffrn_scan_frame_axis.reference_angle (e.g.
     the mean).
