LIGO/Virgo S191105e: No significant candidates in FRAM-TAROT-GRANDMA observations

We performed tiled observations of the LIGO/Virgo S191105e event with the FRAM-Auger (FRAM-A), FRAM-CTA-N (FRAM-C), TAROT-Reunion (TRE), TAROT-Calern (TCA) and TAROT-Chili (TCH) telescopes operating in the r-band and visible located respectively at Pierre Auger observatory (Malargue, Argentina), Roque de los Muchachos observatory (La Palma, Spain), Les Makes astronomical observatory, the Cote d'Azur observatory and La Silla ESO observatory (LaS/ESO). The observation started on 11/08/19 00:10:14 UTC for FRAM-Auger which corresponds approximately to 3456 minutes after the GW trigger time. The observation started on 11/08/19 01:17:32 UTC for FRAM-CTA-N which corresponds approximately to 3523 minutes after the GW trigger time. The observation started on 11/07/19 15:32:23 UTC for TRE which corresponds approximately to 2938 minutes after the GW trigger time. For TCA it started on 11/07/19 22:37:51 UTC which corresponds approximately to 3363 minutes after the GW trigger time. For TCH it started on 11/07/19 23:55:24 UTC which corresponds approximately to 3441 minutes after the GW trigger time.

time of the first and last exposure for a given tile. Observations are not necessarily continuous in this interval. The Probability refers to the 2D spatial probability of the GW skymap enclosed in a given tile. Each FRAM-Auger tile is 1.0x1.0 degrees and 0.45x0.45 degrees for FRAM-CTA-N. Each TRE tile is 4.2x4.2 degrees and 1.9x1.9 degrees for TCA and TCH. These observations cover about 40% of the cumulative probability of the Bayestar skymap available on Nov 6, 2019 18:01:59 UTC. The typical limiting magnitude in R (AB mode) is 16.0 and 18.0 for a 120 s exposure for FRAM-CTA-N and FRAM-Auger, respectively. The typical limiting magnitude in AB mode is 17.0 and 18.0 for a 60.0 s exposure for TRE and TCA/TCH, respectively.
