Bright pixels still present in simulated data #17

I'm still seeing some bright pixels in the simulated data. @kammerje, do you think this is still a reference file issue or could it be to do with the updates to pyNRC? It significantly affects the contrast.

kammerje commented 2 years ago

If this was done with the new simulated data, then these are likely cosmic rays. The question is whether these cosmic rays are correctly flagged by the stage 1 pipeline. If so, we should be using a bad pixel cleaning algorithm before feeding the data into our pipeline. I have a simple script if you are interested. If they are not flagged, then we need to tweak the stage 1 jump detection threshold I think.

Okay great, I'll try your script, I also might play around with adding an additional stage to start from the uncal.fits file. Does NIRCCos output those, or do we have to start with the rateints?

kammerje commented 2 years ago

Ok! NIRCCoS saves them in the pynrc_data folder.
