TESS single-transit search

Search TESS SPOC light curves and cutouts for isolated transits, then audit each against detrending, blending, pointing and prior-art alternatives.

For TESS planet candidates known from a single transit (TOI table: no period, disposition PC or APC), screen their SPOC 120-s light curves for further isolated transit-like dips outside the known transit, with the screen's threshold calibrated on each light curve (sign-flip null) and its completeness measured by injection–recovery. A second dip would constrain the period; its absence is recorded as a bounded null with the measured sensitivity.

Draft campaign — no results

This campaign has not been executed. It has 0 targets, no search log, and no measurements. The specification itself says: “queue built; analysis steps not yet run — do not cite results”. Nothing here is a finding.

Scope

Domain: worlds.planetary.monotransit
Target pool: nasa_exoplanet_archive.toi
Targets: none selected yet

Method 5 steps, run in order

Implementation status is taken from the module register. A step whose module is only designed cannot run yet.

Search log

No search has run

Screened, excluded, rejected and retained counts will be recorded here once the campaign executes. A draft has none.

Negative results and limitations

No results of any kind yet. Known limitations of the plan as written:

The target pool is empty; selection criteria are not yet pinned.

Specification text

# CYGNUS campaign: TESS single-transit candidates, first pass.
# Status: DRAFT. The queue step has been run; the analysis steps are specified and runnable but
# have not been executed. Do not cite results from this file.

objective: >
  For TESS planet candidates known from a single transit (TOI table: no period, disposition PC or
  APC), screen their SPOC 120-s light curves for further isolated transit-like dips outside the
  known transit, with the screen's threshold calibrated on each light curve (sign-flip null) and
  its completeness measured by injection–recovery. A second dip would constrain the period; its
  absence is recorded as a bounded null with the measured sensitivity.

  summary: >
    Declared campaign: screen the light curves of TESS single-transit candidates for further dips,
    with a threshold calibrated per light curve and measured completeness. Only the target queue
    has been built; no light curve has been analysed.
