rgslinepos (rgslinepos-1.7) [xmmsas_20230412_1735-21.0.0]

Description

The position of the center of emission lines is provided per instrument as a function of wavelength, reflection order, and off-axis angle of the source. This task is useful, when off-axis pointings are evaluated in order to optimize the coverage of the emission spectrum by the RGS detector, e.g. if the intention is to avoid inter-chip gaps.

Output is per wavelength the CCD number and the dispersion coordinate in CHIPCOORD system.
