slit loss correction in the pipeline? #192

Closed Vladan1986 closed 6 months ago

Vladan1986 commented 6 months ago

Hello,

I have a question regarding the slit-loss corrections applied to the JWST spectra. I was wondering if (and how) the slit losses are addressed in your pipeline on the prism spectra.

According to what I found on the DAWN website regarding the data reduction (https://ui.adsabs.harvard.edu/abs/2023arXiv230600647H/abstract), the polynomial function was applied to correct for the slit-losses, but I am not sure if this is the case for the entire DAWN sample, or only for the sources mentioned in that work.

Thank you in advance.

Cheers,

I think this issue might be better raised on the DJA github page, as it pertains to pipeline steps outside of grizli. I believe grizli is only used to generate the photometry on the corresponding NIRCam imaging which is then used as input to scale the spectroscopy.
