# Sliding-box dip search with injection-recovery for TESS light curves

Extend the TESS dip record to the 2024 sectors with a detrending window long enough to keep day-long dips, and quantify what depth would have been seen.

Inputs

The flat-CSV TESS dataset; one product per sector (SPOC 120 s preferred, otherwise QLP; for QLP the KSPSAP `det_flux` column).

Output

tess_results.json (deepest candidate per sector, number of candidates at SNR >= 7, recovery fractions per depth x duration, a background-decorrelated SAP cross-check for QLP sectors) and one figure per sector.
