Description:
Symbols:
The symbol(s) listed here will be used below to coordinate datasets with the same shape.
nP: Number of points
- Groups cited:
NXattenuator, NXdata, NXdetector, NXentry, NXinstrument, NXsample
Structure:
entry: (required) NXentry
definition: (required) NX_CHAR
Official NeXus NXDL schema to which this file conforms.
Obligatory value:
NXxrot
instrument: (required) NXinstrument
detector: (required) NXdetector
polar_angle: (required) NX_FLOAT {units=NX_ANGLE}
The polar_angle (two theta) where the detector is placed.
beam_center_x: (required) NX_FLOAT {units=NX_LENGTH}
This is the x position where the direct beam would hit the detector. This is a length, not a pixel position, and can be outside of the actual detector.
beam_center_y: (required) NX_FLOAT {units=NX_LENGTH}
This is the y position where the direct beam would hit the detector. This is a length, not a pixel position, and can be outside of the actual detector.
attenuator: (required) NXattenuator
sample: (required) NXsample
rotation_angle: (required) NX_FLOAT (Rank: 1, Dimensions: [nP]) {units=NX_ANGLE}
This is an array holding the sample rotation start angle at each scan point
rotation_angle_step: (required) NX_FLOAT (Rank: 1, Dimensions: [nP]) {units=NX_ANGLE}
This is an array holding the step made for sample rotation angle at each scan point
name: (required) NXdata
rotation_angle: link (suggested target:
/NXentry/NXsample/rotation_angle
