AT 2021hdr: a candidate tidal disruption of a gas cloud by a binary super massive black hole system

In this dataset we provide tables for the Zwicky Transient Facility (ZTF) and Swift observations presented in the paper "AT 2021hdr: a candidate tidal disruption of a gas cloud by a binary super massive black hole system", accepted for publication in the Astronomy and Astrophysics Journal (Hernández-García et al. 2024). Files description: -ztf_table:_zenodo.csv: Log of the ZTF forced photometry observations. Include the dates in MJD, filter, apparent magnitudes, and difference fluxes. - swift_table_zenodo.csv: Log of the Swift observations, including the observation ID, date (in MJD), exposure time, count-rate in the 0.5-10 keV energy band, and UV fluxes in the UVW2 and UVM2 filters.
