NIRSpec Piratical Pipeline

Plunder spectra from the JWST archive.

FAQ/things to note

Q: Code won’t run, pipeline crashes

A: Based on our testing the most likely cause for this is incompatible/bugged versions of one or more of the STScI python packages the jwst pipeline depends on, try upgrading these to the latest version.

Q: I’m getting errors that say something about the CRDS server connection failing

A: To run the JWST pipeline you need to set some environment variables so the pipeline can download calibration files, details available here: here. Sometimes the CRDS server seems to go down and you might need to wait a few hours to be able to connect to it again.

Q: A step in the pipeline is failing, potentially saying something about missing ASDF or cannot reshape array?

A: You might have a partially downloaded rate or uncal file (depending on whether you’re skipping the L1 pipeline or not). Look in the uncal_files or rate_files directory for one or more files that are smaller than the others, try deleting them and running again. In the longer term we’ll try to write something into the pipeline to automatically detect this.
