RomanCoronagraph¶

class webbpsf.RomanCoronagraph(mode=None, pixelscale=None, fov_arcsec=None, apply_static_opd=False)[source]¶

Bases: RomanInstrument

Roman Coronagraph Instrument

Simulates the PSF of the Roman coronagraph.

Current functionality is limited to the Shaped Pupil Coronagraph (SPC) observing modes, and these modes are only simulated with static, unaberrated wavefronts, without relay optics and without DM control. The design represented here is an approximation to a baseline concept, and will be subject to change based on trades studies and technology development.

Parameters:

modestr: Roman Coronagraph Instrument observing mode. If not specified, the __init__ function will set this to a default mode ‘CHARSPC_F660’
pixelscalefloat: Detector pixelscale. If not specified, the pixelscale will default to 0.02 arcsec for configurations usint the IMAGER camera and 0.025 arcsec for the IFS.
fov_arcsecfloat: Field of view in arcseconds. If not specified, the field of view will default to 3.20 arcsec for the IMAGER camera and 1.76 arcsec for the IFS.
