Masks 1.5 transit durations wide erase aligned box transits at 74.846914 days in 37 TOI-700 TESS sectors
We test how masks for four known planets change transit-depth information in 37 public TESS sectors of TOI-700. We use 585,515 clean samples at a cadence of 120 seconds. Test signals have periods from 45 to 90 days and central, circular, Earth-radius durations. The primary model uses boxes, fixed times and shapes, sector constants, and equal independent noise. Masks have a total width of 1.5 times each known transit duration. They remove 3.08156% of all clean samples. At 74.846914 days, twice planet d's period, they remove every sampled test transit in both aligned classes. Joint models retain 55.5% and 68.0% of the reference depth information with four shared known-planet depths. They retain 25.6% and 27.6% with separate depths per sector. A 0.1-day period grid misses the complete loss. A geometric bound gives a continuous interval of complete loss for the box model. Shape, weight, baseline, mask-width, direct-projection, and Gaussian-noise checks test the calculation. The package preserves lossless source columns, original-file checks, code, full maps, and figures. This is a conditional sensitivity result. It does not establish a planet or measure real-noise search completeness.

We reuse exact TIME, SAP_FLUX, SAP_FLUX_ERR, and QUALITY columns from its 37 TESS sectors. We preserve its source manifest and check all reused rows against the original MAST FITS files. This work uses a new row selection and a new information calculation.

Prior work showed that removing known transits can hide additional planets. It provides context for this target-specific information map.

Prior work measured detection losses due to transit multiplicity. The present calculation measures fixed-shape depth information under stated masks.

We use its exact MAST source manifest and parameter record. We download and hash-check all original FITS files again.

We adopt its 1.5-duration mask width as one stated policy and use the established conditional-information framework. We use new Kepler inputs and new code.

This work supplies the two fixed clocks, the source manifest, and the earlier native extracts. It calculated mask losses and joint-fit information. We fit the measured flux and test noise and shape effects.
- usesFits with free sibling event depths retain at least 86.1% of target information in 763 Kepler box models with fixed times and equal independent noise
This prior study compared masks with conditional information from shared and per-sector transit depths in TOI-700. We use the established method with separate depths for every sibling event in a new Kepler sample.
