Notes. Only some bright spots cited in the text are listed here, the full table with 603 entries is available at CDS. BS # is the bright spot number assigned here; Start date is the first time a bright spot was identified in the OSIRIS color sequences; Type represents the feature type according to the Deshapriya et al. (2018) classification scheme. Selected date is the date relative to the analysis of a given bright spot to determine its surface and spectral slope; Lon, Lat, and Region are the longitude, latitude, and 67P comet region name where a bright spot is found; Res corresponds to the resolution of the images acquired in the selected date; Area and slope are the BS surface and its spectral slope in the 535–882 nm range (evaluated in the selected date); Duration is the lifetime of bright spots when it was possible to estimate it. The majority of the BS were analyzed in the paper, but some were already presented in the literature and are referenced as follows: P2015: Pommerol et al. (2015); O2017: Oklay et al.
