As of right now, the core.datacube.compute_weights() routine that is called during the creation of a datacube computes weights by extracting a spectrum from the single brightest pixel from the white l…

Hi, I got unexpected results when DRP transformed the 2D sky-subtracted frame into 3D cubes. In some of the pixels, the emission line features are extremely strong (~50K), almost reaching the saturati…

Hi!
I just noticed that the current version of the pipeline seems to miss the saturation check.
The IDL pipeline performs the check at stage 1, right after the images are loaded and before the …

Hello,
I opened an issue in February (#126 ) that was mostly solved, but I had an additional question that was never addressed. One night in particular has not successfully reduced. It fails to pro…

Running `pypeit_coadd_datacube` on KCWI data produces a datacube that has an incorrect WCS - what should be the central coordinate ends up in the top left of the image. It's not clear to me whether th…

Dear Luca and Josh,
We are reaching out for some guidance. We reduced our recent KCWI data (medium slicer, no blue filter, 2x2 binning) and found that the continuum emission in the final reduced I…

In the flat fielding process, the DRP takes in twilight, dome, and internal flats and makes master versions of each. In the CorrectIllumination class, does the reduction use the twilight flats to corr…

The readthedocs description of the pipeline products needs a bit of work. This is somewhat related to (retired) issues #38 and #39
1) Divide the table into engineering and science data products. F…
