Documentation for data resulting from McNeill et al. (2023) - An Untargeted Survey of the Rotational Properties of Main Belt Asteroids using the Transiting Exoplanet Survey Satellite (TESS) -- 3sig_Cycle1.txt - Contains the extracted photometric data for all objects found in Cycle 1 with a single round of sigma-clipping carried out at the 3-sigma level for each individual object. Note that this is only minimally effective for objects with few data points. desig - Minor Planet Designation of the object mjd - The Modified Julian Date of the observation relative_hours - The time of the observation expressed in hours where the zero point is defined by the first observation. mag - The instrumental magnitude of the object at this time-stamp. These values have not been calibrated to a true magnitude but have been corrected for both distance and phase-angle effects. magerr - The photometric uncertainty on each brightness measurement -- finaltable_LCDBQualityFlag_True.txt - Contains the overall derived results obtained for each object in Cycle 1 for which there were more than 50 total individual detections (prior to outlier removal). Object Id - Minor Planet Designation of the object Amplitude - Peak-to-trough amplitude (in magnitudes) of the Fourier fit to the folded lightcurve Num. Obs. - Total number of observations in Cycle 1 LS Norm. Power - The normalised Lomb Scargle power of the peak signal in the periodogram for this object. Rot. Period (h) - The best-fit rotation period in hours Prob.(Exact) - The confidence value that this rotation period is correct to within 3% Prob.(Aliased) - The confidence value that this rotation period is correct or is a factor of 2 from the correct period. -- TESS_Results_gt200pts.txt - A summary table for the derived results also including a comparison with results obtained by Pal et al. (2020) obj - Minor Planet Designation of the object P - The best-fit rotation period in hours P_err - The uncertainty on the rotation period A - Peak-to-trough amplitude (in magnitudes) of the Fourier fit to the folded lightcurve CV_exact - The confidence value that this rotation period is correct to within 3% CV_alias - The confidence value that this rotation period is correct to within 3% or is a factor of 2 from the correct period. Match? - Does the rotation period derived in this work match the result of Pal et al. (2020). Y/N/- denoting yes, no and no result from Pal. --
