make_vlt_aperture
- hcipy.aperture.make_vlt_aperture(normalized=False, telescope='ut3', with_spiders=True, with_M3_cover=False, return_segments=False)
Make the VLT aperture.
This aperture is based on the ERIS pupil documentation: VLT-SPE-AES-11310-0006.
- Parameters:
- normalizedboolean
If this is True, the outer diameter will be scaled to 1. Otherwise, the diameter of the pupil will be 8.0 meters for UT1-3 and 8.1196 meters for UT4.
- telescopeone of {‘ut1’, ‘ut2’, ‘ut3’, ‘ut4’, ‘antu’, ‘kueyen’, ‘melipal’, ‘yepun’}
The specific telescope on the VLT, case insensitive. Default: UT3.
- with_spidersboolean
If this is False, the spiders will be left out. Default: True.
- with_M3_coverboolean
If this is True, a cover will be created for the M3 in stowed position. This M3 cover is only available on UT4, mimicking the ERIS pupil. A warning will be emitted when using an M3 cover with other UTs. Default: False.
- return_segmentsboolean
If this is True, the pupil quadrants (segments) will also be returned.
- Returns:
- apertureField generator
The VLT aperture.
- segmentslist of Field generators
The segments. Only returned when return_segments is True.
