cds-question@unistra.frasteroidssurveysphotometryvisible-astronomyDeriving high-quality light curves for asteroids and other periodic sources from survey data is challenging owing to many factors, including the sparsely sampled observational record and diurnal aliasing, which is a signature imparted into the periodic signal of a source that is a function of the observing schedule of ground-based telescopes. In this paper we examine the utility of combining asteroid observational records from the Zwicky Transient Facility and the Transiting Exoplanet Survey Satellite, which are the ground- and space-based facilities, respectively, to determine to what degree the data from the space-based facility can suppress diurnal aliases. Furthermore, we examine several optimizations that are used to derive the rotation periods of asteroids, which we then compare to the reported rotation periods in the literature. Through this analysis we find that we can reliably derive the rotation periods for ~85% of our sample of 222 objects that are also reported in the literature and that the remaining ~15% are difficult to reliably derive, as many are asteroids that are insufficiently elongated, which produces a light curve with an insufficient amplitude and, consequently, an incorrect rotation period. We also investigate a binary classification method that biases against reporting incorrect rotation periods. We conclude the paper by assessing the utility of using other ground- or space-based facilities as companion telescopes to the forthcoming Rubin Observatory.2024AJ....168..181Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/168/181CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/astorb : Orbits of Minor Planets (Bowell+, 2014-)J/ApJ/763/32 : Galactic halo RRab stars from CSS (Drake+, 2013)J/AJ/155/39 : Variability of TIC sources with KELT (Oelkers+, 2018)J/AJ/166/152 : Main Belt Asteroid Rotation from TESS (McNeill+, 2023)J/A+A/693/A66 : Asteroid rotation periods from TESS (Vavilov+, 2025)http://www.minorplanet.info/ : MinorPlanet.info home page (which gives accesshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/168/181https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/168/181http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/168/181https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/168/181https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/168/181http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/168/181GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/168/181/table5*SS1+TESSC1 rotation periods and amplitudes for the 1623 objects with high confidence (~85%)recnoRecord number assigned by the VizieR team.
