Description

This instrument is the conventional cold-source triple-axis spectrometer TAS1
at Risoe National Laboratory. It does not exist anymore, but was used as the
first detailed work performed with the McStas package.
Here it is used as a diffractometer for monochromator rocking curves. The
detector is at the sample position.

Input parameters

Parameters in boldface are required; the others are optional.
