_diffrn_measurement.rotation_mode
Name:_diffrn_measurement.rotation_mode
Definition:
Code describing the technique used to sample as completely as possible
the accessible range of reciprocal space.
Type: Code
The data value must be one of the following:
|
rotation | The detector records diffracted intensities continuously while the sample is rotated. |
|
stepwise | The detector records diffracted intensities while the sample is stationary and the beam is either steady or performing a defined motion, typically precessing around a conical surface normal to the sample (precession electron diffraction). |
