3.4.29. NXxnb

Status:

application definition, extends NXxbase, version 1.0b

Description:

This is the application definition for raw data from a single crystal diffractometer measuring in normal beam mode. It extends NXxbase, so the full definition is the content of NXxbase plus the data defined here. All angles are logged in order to support arbitrary scans in reciprocal space.

polar_angle[np]: NX_FLOAT {units=NX_ANGLE}

The polar_angle (gamma) of the detector for each scan point.

tilt_angle[np]: NX_FLOAT {units=NX_ANGLE}

The angle by which the detector has been tilted out of the scattering plane.

sample: NXsample

rotation_angle[np]: NX_FLOAT {units=NX_ANGLE}

This is an array holding the sample rotation angle at each scan point
