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.
