Create a more robust process to mask known companions #27

Open AarynnCarter opened 2 years ago

AarynnCarter commented 2 years ago

At the moment companions are being masked both in the raw and calibrated contrast calculation using a simple circular mask with radius N*fwhm for that filter. Issues with this are:

1) The value of N is different between NIRCam and MIRI, but isn't specific to a given filter. 2) A circle is a naive mask to use for the JWST PSF's, particularly those from NIRCam, which have lobes arranged in a hexagonal pattern.

A better method might be to use a forward modelled PSF of an injected companion to identify which specific pixels need to be masked.

Still not done in version 2; this remains relevant.
