Planodia transit search: TESS sector 3 (raw results and candidates)

What this is. The complete, unfiltered result of the Planodia transit search for TESS sector 3: 205,551 light curves were searched for repeating dips by volunteers on the volunteer-computing project bitboinc (https://bitboinc.athena.org.tr); every task was computed by two different volunteers and accepted only when both results agreed. Planodia searches the TESS brightness record of each star for the small, regular dimming a planet causes when it passes in front of its star. An explanation and progress are at https://bitboinc.athena.org.tr/planodia.php. How the numbers were obtained Light curves. TESS Quick-Look Pipeline (QLP) full-frame light curves from MAST (HLSP). The raw aperture flux (SAP_FLUX) is used; the flux is flattened with a running median. Search. A binned box-least-squares (BLS) search over a grid of frequencies. After subtracting the noise floor the periodogram is converted to a signal detection efficiency (SDE); the five strongest peaks of each light curve are kept, with period, duration, depth, signal-to-noise, time of the first transit and number of transits. Candidates. Light curves whose best peak reaches SDE ≥ 8 contribute their three strongest peaks to the candidate table, which is compared automatically with the TESS Objects of Interest (ExoFOP) and the TESS eclipsing-binary catalogue (Prsa et al. 2022); some candidates were also looked at by hand. Files in this record planodia_s03_search1_raw.txt.gz: raw output of the first search, all light curves. A line "# wu=<task> result=<id> ..." starts each task's block; then one line per light curve: TIC, Tmag, number of points, SDE of the best peak, number of peaks and, for each peak, six numbers: period [d], duration [d], depth [ppm], signal-to-noise, time of the first transit [BTJD = BJD − 2457000], number of transits. planodia_s03_candidates.csv.gz: the candidate table (45,087 rows): tic, src (0 = first search), tmag, sde, peak_rank (1 = strongest), period [d], duration [d], depth_ppm, snr, tc [BTJD], n_transits, status (new, known_toi, known_eb, rejected, promising or submitted: the result of the cross-match and of the hand check at the date of this record). README.txt: this description in plain text. How to read these data These are automatic detections. Most strong signals are eclipsing binaries, blended neighbours or instrument effects; only follow-up observations can show whether a signal is a planet. The SDE and the other numbers are search statistics, not probabilities, and no false-alarm correction has been applied. Volunteers 20 volunteers returned validated results for this sector. Volunteers who asked to be named: Anand Bhat (Australia), Dmytro Taukchi (Ukraine), Erik Veit (United States), Hans Sveen (Norway), Henk Haneveld (Netherlands), Ian Dickinson (United Kingdom), Johannes Rensen (Netherlands), José Miguel (Spain), Michael Doneske (United States), Michael Dörscheln (Germany), Mirko Tomaschek (Libya), Thomas Kledzik (Germany), Yevhen Vasiliu (Ukraine); and 7 other volunteers who preferred to stay anonymous.
