MetisLMSEfficiency

Computes the grating efficiency (blaze function) for the METIS LMS.

The procedure is described in E-REP-ATC-MET-1016_1.0. For a given order (determined by the central wavelength) the grating efficiency is modelled as a squared sinc function of wavelength via the grating angle.

MetisLMSImageSlicer

Treats the METIS LMS image slicer as an aperture mask effect.

This helps in building a FieldOfView object that combines the spatial field of the slicer with the spectral range covered by the LMS setting.

The effect differs from its parent class ApertureMask in the initialisation from the Aperture List extension of the trace file !OBS.trace_file.
