\nFRAM-Auger, TAROT-Calern (TCA) and TAROT-Chili (TCH) \ntelescopes, operating in the R-band for FRAM and Clear for TAROT, located \nrespectively at Pierre Auger Observatory (Malargue, Argentina),

\ntelescope in degrees and the typical magnitude in R (AB mag) for a \ngiven exposure in seconds.\n\n+-------------+---------+----------+-----------+------------+\n| Telescope | Delay | Filter |
