This page keeps track of tilt events observed on TSO datasets. We identify CANDIDATE tilt events from TSOs based on different metrics (flux variations, FWHM, etc.) and change those to CONFIRMED based on WFS analyses/feedback.
2022
Date | Target | PID / Obs | Instrument(s) used for detection | Detection method | Status | Comments |
---|---|---|---|---|---|---|
2022-05-02 | Transit of HAT-P-14b | 1442 / 1 | NIRcam SW/LW + FGS | Flux "jump" (in NIRCam and FGS), FWHM "jump", centroid "jump" | CONFIRMED | See Schlawin+2022. Event at about 2459701.94 JD. |
2022-06-08 | Transit of HAT-P-14b | 1541 / 1 | NIRISS SOSS | Flux "bumps" (both in Order 1 and 2), FWHM | CANDIDATE | 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. |
2022-07-30 | Transit of WASP-39b | 1366 / 3 | NIRSpec/BOTS G395H + FGS | Flux "jump", FWHM "jump", centroid "jump". | CONFIRMED | |
2022-08-11 | Eclipse of WASP-18b | 1366 / 21 | NIRISS SOSS + FGS | Flux "jump", FWHM "jump", centroid "jump". | CONFIRMED | Tilt event seems to be very small, suggesting (again) SOSS is very sensitive to these. FWHM jump is obvious in the data. |
