Some users (Jen van Saders and Max Guenther) pointed out a few use cases for TESS-SIP, and I've updated based on their experiences.

Changes:

  • TESSCut TPFs can now be run in TESS-SIP: we can now use FFI TPFs in TESS-SIP
  • Running background periodograms: It's sometimes difficult to tell apart the true period from TESS periodicities. To help with this, I've added the ability to automatically run the periodogram on the background pixels too, i.e. the pixels outside of the aperture. This means that we have a periodogram of the background at the same time. Any period that is consistent with the background is probably spurious.
  • Added the ability to select the number of PCA components.
