NIRISS SOSS psfs are identical for CLEAR and F277W filters #227

Closed hover2pi closed 5 years ago

hover2pi commented 5 years ago

I noticed that if I generate a NIRISS psf using pupil GR700XD and filter CLEAR or F277W, I get identical psfs returned. They should be different!

Here's the code I used:

import webbpsf
ns = webbpsf.NIRISS()
ns.pupil_mask = 'GR700XD'
ns.filter = 'CLEAR'
clear = ns.calc_psf(monochromatic=1E-6, oversample=1)
ns.filter = 'F277W'
f277w = ns.calc_psf(monochromatic=1E-6, oversample=1)
np.all(clear == f277w)

Is it the case that only the CLEAR filter is supported with GR700XD or am I mistaken? And if not, are there plans to add support for the F277W filter? Thanks!

Hi @hover2pi - apologies for not responding to this before now. We're actually using the repo in spacetelescope/webbpsf as the main development repo now, so I'll refile this as an issue of there.
