(TRE), 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), Les Makes \nAstronomical Observatory, the Cote d'Azur Observatory and La Silla ESO \n(LaS/ESO).\n\nThe following table shows for each telescope: the delay in minutes from\nthe trigger, which filter is used, the field of view of the telescope in \ndegrees and the typical magnitude (AB mag) for a given exposure in \nseconds:\n+-------------+---------+----------+-----------+------------+\n| Telescope   | Delay
