3.3.2.7. NXiqproc

Status:

application definition, extends NXobject

Description:

Application definition for any \(I(Q)\) data.

Symbols:

The symbol(s) listed here will be used below to coordinate datasets with the same shape.

nVars: The number of values taken by the varied variable

nQX: Number of values for the first dimension of Q

nQY: Number of values for the second dimension of Q

Groups cited:

NXdata, NXentry, NXinstrument, NXparameters, NXprocess, NXsample, NXsource

Structure:

ENTRY: (required) NXentry

@entry: (required) NX_CHAR

title: (required) NX_CHAR

definition: (required) NX_CHAR

Official NeXus NXDL schema to which this file conforms

Obligatory value: NXiqproc

instrument: (required) NXinstrument

name: (required) NX_CHAR

Name of the instrument from which this data was reduced.

SOURCE: (required) NXsource

type: (required) NX_CHAR

name: (required) NX_CHAR

probe: (required) NX_CHAR

Any of these values: neutron | x-ray | electron

SAMPLE: (required) NXsample

name: (required) NX_CHAR

Descriptive name of sample

reduction: (required) NXprocess

program: (required) NX_CHAR

version: (required) NX_CHAR

input: (required) NXparameters

Input parameters for the reduction program used

filenames: (required) NX_CHAR

Raw data files used to generate this I(Q)

output: (required) NXparameters

Eventual output parameters from the data reduction program used

DATA: (required) NXdata

data: (required) NX_INT (Rank: 3, Dimensions: [nVars, nQX, nQY])

This is I(Q). The client has to analyse the dimensions of I(Q). Often, multiple I(Q) for various environment conditions are measured; that would be the first dimension. Q can be multidimensional, this accounts for the further dimensions in the data

variable: (required) NX_NUMBER (Rank: 1, Dimensions: [nVars])

@varied_variable: (required) NX_CHAR

The real name of the varied variable in the first dim of data, temperature, P, MF etc…

qx: (required) NX_NUMBER (Rank: 1, Dimensions: [nQX])

Values for the first dimension of Q

qy: (required) NX_NUMBER (Rank: 1, Dimensions: [nQY])

Values for the second dimension of Q
