Template/test instrument for Grating_trans

Identification

A simple test insrument for the transmission grating component. Two examples
of gratings are included matching those in the Chandra X-ray Observatory

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
E0	keV	Central energy to emit from the source.	1
dE	kEV	Half energy spread of source.	0.001
GD	m	Distance from grating to detector.	1
Rx	deg	Rotation of grating around the X-axis.	0
Ry	deg	Rotation of grating around the Y-axis.	0
Rz	deg	Rotation of grating around the Z-axis.	0
MEG		Flag to chosse between the two included gratings. 1: medium energy grating (MEG), 0: high energy grating (HEG).	0
