Item Description

The increment for each step for the specified axis in degrees. In general, this will agree with _diffrn_scan_frame_axis.angle_increment. The sum of the values of _diffrn_scan_frame_axis.angle and _diffrn_scan_frame_axis.angle_increment is the angular setting of the axis at the end of the integration time for a given frame. If the individual frame values vary, then the value of _diffrn_scan_axis.angle_increment will be representative of the ensemble of values of _diffrn_scan_frame_axis.angle_increment (e.g. the mean).
