  • What is a "tilt" event? Read the description for TSO'ers in JDox.
  • Can I report a "tilt" event in public data that is not in the list below? Yes, please!  Please reach Reach out to Nestor Espinoza if you find one and he'll tabulate it below.
  • Can I report a "tilt" event of my propietary data? Yes, that would be fantastic. However, we need direct consent from the PI(s) of the program to tabulate it below. If you have a reference (e.g., a published paper), even better. Please reach out to Nestor Espinoza if you find one and he'll tabulate it below.

See Schlawin+2022. Event at about 2459701.94 JD. Event identified to be on C6 and C1 segments.

This seems to be a different tilt event flavor, with a trend in the FWHM rather than a jump in it. Various analyses done by Nestor Espinoza. It doesn't appear on FGS telemetry flux count.

2022-06-21Transit of WASP-96b2734 / 2NIRISS/SOSS (+ FGS?)FWHM "jump", but no apparent impact on white-light photometry.

This event didn't produce a measurable flux "bump", but it shows a clear FWHM "jump" signature. FGS shows what appears to be a small (500 ppm) flux jump at 2459751.86 JD — but the BJD TDB time for the event in SOSS is about 2459751.88 — so a 30-min difference.

Tilt event seems to be very small, suggesting (again) SOSS is very sensitive to these. FWHM jump is obvious in the data. Event likely on B6 segment.
