MIRI

class stpsf.MIRI[source]

Bases: JWInstrument_with_IFU

A class modeling the optics of MIRI, the Mid-InfraRed Instrument.

Relevant attributes include filter, image_mask, and pupil_mask.

The pupil will auto-select appropriate values for the coronagraphic filters if the auto_pupil attribute is set True (which is the default).

Special Options:

The ‘coron_shift_x’ and ‘coron_shift_y’ options offset a coronagraphic mask in order to produce PSFs centered in the output image, rather than offsetting the PSF. This is useful for direct PSF convolutions. Values are in arcsec. ` miri.options['coron_shift_x'] = 3 # Shifts mask 3" to right; or source 3" to left. `

Attributes Summary

`aperturename`	SIAF aperture name for detector pixel to sky coords transformations
`band`	MRS IFU spectral band.
`filter`	Currently selected filter name (e.g. F200W).
