Abstract

We present photometric data for minor planets observed by the Transiting Exoplanet Survey Satellite during its Cycle 1 operations. In total we extracted usable detections for 37,965 objects. We present an examination of the reliability of the rotation period and lightcurve amplitudes derived from each object based upon the number of detections and the normalised Lomb-Scargle power of our period fitting and compare and contrast our results with previous similar works. We show that for objects with 200 or more photometric detections and a derived normalised, generalised Lomb-Scargle power greater than 0.2 we have an 85% confidence in that period - this encompasses 3492 rotation periods we consider to be highly reliable. We independently examine a series of periods first reported by P al et al. (2020) - periods derived in both works found to have similar results should be considered reliable. Additionally we demonstrate the need to properly account for the true proportion of slow rotators (P > 100 h) when inferring shape distribution from sparse photometry.
