## Description

    A test of the PreMonitor_nD component showing the effective usable part
    reflected from a monochromator.

    Example: ETA=1 lambda=1 Detector: Mon_Sample=1.36e+08

## Input parameters

Parameters in boldface are required; the others are optional.

Name | Unit | Description | Default
lambda | Angs | Wavelength at monochromator, computed from DM and THETA_M if left as 0. | 1
DM | Angs | d-spacing of monochromator, computed from lambda and THETA_M if left as 0. | 3.355
RV | m | Monochromator vertical curvature, 0 for flat, -1 for automatic setting | -1
RH |  |  | -1
L1 | m | Source-Monochromator distance | 17
L2 | m | Monochromator-Sample distance | 3.2
ETA | min | Monochromator mosaic (gaussian) | 30
verbose | 1 | Print DIF configuration. 0 to be quiet | 1
THETA_M | deg | Monochromator take-off angle, computed from lambda and DM if left as 0. | 0
SM | 1 | Scattering sense of beam from Monochromator. 1:left, -1:right | 1
