Last meeting's TODO's

• Raw Data handling:

  • Check cadence: 2min cadence
  • Use only SPOC data:
    • Restrict lk search to author=SPOC
    • Filter ExoFop candidates to only those with source=SPOC
      • this reduces TOIs 5K -> 1.7K (https://github.com/dfm/tess-atlas/pull/168)
      • Source = Parameter Source Pipeline - This column lists the data analysis pipeline which initially identified the planet candidate
      • Pipeline = Detection Pipeline(s) = This column lists the pipeline which generated the current set of parameters for a given TOI.
      • https://tess.mit.edu/news/toi-catalog-now-includes-the-detection-pipeline-for-each-candidate/
  • Adjusted quality-bitmask to hard instead of default (not using hardest as not recommended)
  • Adjusted lk.remove_outliers to prevent sigma clipping (see https://github.com/dfm/tess-atlas/pull/171)

• phase plot issue: GP not subtracted from flux:

  • Compute mu=GP.predict(residuals) in post-proc and subtract out from flux (see https://github.com/dfm/tess-atlas/issues/173)

Bulk analysis results (from last meeting)

We didn't finish going over all the TOIs in the last meeting:

• Ran analysis on all TOIs, documented here: https://github.com/dfm/tess-atlas/issues/166
• Some TOI fits look strange, documented here: https://github.com/dfm/tess-atlas/issues/167
• Results:
  • webpages: http://catalog.tess-atlas.cloud.edu.au/_build/html/
  • files: http://catalog.tess-atlas.cloud.edu.au/content/toi_notebooks/toi_103_files/

More questions:

• What diagnostic plots can I make?
• Shall we try to see if the initial guess is good? (https://github.com/dfm/tess-atlas/issues/101)

Action Items:

• Manually run TOI 178 (multiplanet) TOI 237 (potentially multi-modal fit?)
• Make and save diagnostic plots (binned data, corner, traces, SNR?)
• Look at phase-plots and divide erroneous fits in categories
  • eg. wrong period init https://github.com/dfm/tess-atlas/issues/101
• use the quality flag --> hardest (not a big deal if we delete extra data)
• remove EXOFOP source=SPOC filter once complete with debugging
