3.3.2.17. NXsqom¶
Status:
application definition, extends NXobject
Description:
This is the application definition for S(Q,OM) processed data.
As this kind of data is in general not on a rectangular grid after data reduction, it is stored as Q,E positions plus their intensity, table like. It is the task of a possible visualisation program to regrid this data in a sensible way.
Symbols:
The symbol(s) listed here will be used below to coordinate datasets with the same shape.
nP: Number of points
