NIRISS GR700XD model PSFs in webbpsf

1

This is a follow-up from an email about this issue. The model in webbpsf for the GR700XD grating still uses the original prototype Bach grating parameters, not the flight LLNL...

Hi all, I've been using the webbpsf.setup_sim_to_match_data function to simulate some NIRCam non-coronagraphic data recently. Thanks for adding this functionality, it's really useful. However, I found the description in the...

As discussed with @skendrew and Achrene Dyrek, it could be useful to have a model for the dispersed LRS "PSF" (not really a PSF but a spectrum of PSFs). Achrene...

I don't understand how/why this wasn't already implemented. It's in the data files. May have just been an oversight accidentally .

Issue with convolution over pixel using astropy.convolution.Box2DKernel?

I've been doing some Roman simulations and comparing the input simulated positions with the measured positions using photutils and the webbpsf gridded_psf routines. I eventually noticed that I got good...

Work in progress to add functionality for the MIRI IFU - Medium Resolution Spectrometer. Added quite a few changes to `webbpsf_core.py:MIRI` to accommodate the instrument setup for the MRS. -...

Improvements in MIRI LRS instrument model

Digging into MIRI LRS for some science, I'm finding parts of the LRS mode model in webbpsf that can be improved / fixed - [ ] Pupil stop is correctly...

Improved MIRI cruciform model using Fresnel diffraction

@merope82 informs me that @patapisp has developed an improved model of the cruciform effect seen in MIRI detectors. @patapisp tells me he intends to (eventually) contribute this to webbpsf, but...
