Phase-folded light curves (top) and location of the Trumpler 5 RRL in the Period-Amplitude diagram (bottom) for the four surveys with publicly available time series data. From left to right : Gaia (Clementini et al. 2023), PS1 (Sesar et al. 2017b), ASAS-SN (Jayasinghe et al. 2019a), and OGLE-IV (Soszynski et al. 2016). In the bottom row, the location of the Trumpler 5 RRL (star symbol) is shown in comparison to RRLs from each survey in the selected band. See text for details. Error bars for the magnitudes are plotted in all panels in the top row but are smaller than the symbol size in all cases except for ASAS-SN.
