General questions

  1. Is grizli using the same grismconf as Nor's code (e.g. does it import https://github.com/npirzkal/GRISMCONF)?
  2. How hard might it be to segregate all FITS and FITS-WCS dependencies into separate I/O routines (as a step towards moving over to ASDF + gWCS)?
  3. Is EAZY a strict dependency? 
  4. Looks like it's using pysynphot instead of synphot_refactor. Have you looked at updating?

Model based extractionModel-based extraction:

  1. How does grizli specify parameters to vary?
  2. What is the merit-function for the fit? 
  3. How are the data weighted ?
  4. What optimizer is used?
  5. How are uncertainties calculated?
  6. Which modules/functions/classes are doing the fitting?


GrismDisperser

  • In model.GrismDisperser, do compute_model and compute_model_psf correspond to pixel- and object-based dispersion, respectively?
