NXrefscan

Status:

application definition, extends NXobject

Description:

This is an application definition for a monochromatic scanning reflectometer.

It does not have the information to calculate the resolution since it does not have any apertures.

Symbols:

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

nP: Number of points
