Upper limits for multiple positions
Find upper limits for a list of positions given by an uploaded file. For reference, please read the paper Tubín-Arenas et al. (2024) and the appropriate page here for your survey (DR1 and DR2). Please reference Tubín-Arenas et al. (2024) and Merloni et al. (2024) (for DR1) or Ramos-Ceja et al. (2026) (for DR2) if these upper limits are used. There also exists APIs to obtain upper limits programmatically.
