Abstract

We performed tiled observations of LIGO/Virgo S200219ac event with the FRAM-CTA-N, TAROT-Calern (TCA), TAROT-Chili (TCH), TAROT-Reunion (TRE) telescopes. FRAM-CTA-N is located at Observatorio del Roque de los Muchachos. TCA is located at Calern site at the Cote d'Azur observatory. TCH is located at La Silla ESO observatory (LaS/ESO). TRE is located at Les Makes astronomical observatory. The following table shows for each telescope: the delay in minutes from the trigger, which filter is used, the field of view of the telescope in degrees and the typical limiting magnitude (AB mag) for a given exposure in seconds (s). +-------------+---------+----------+-------------+------------+ | Telescope | Delay | Filter | f.o.v. | Limiting | | | [min] | | [deg] | Mag. | |-------------+---------+----------+-------------+------------| | FRAM-CTA-N | 799 | R | 0.45 x 0.45 | 17.0 (90s) | | TCA | 512 | Clear | 1.9 x 1.9 | 18.0 (60s) | | TCH | 878 | Clear | 1.9 x 1.9 | 18.0 (60s) | | TRE | 367 | Clear | 4.2 x 4.2 | 17.0 (60s) | +-------------+---------+----------+-------------+------------+ We performed the following joint tiled observations [1] : +-------------+------------+------------+---------+---------+---------+ | Telescope | TStart | TEnd | RA | DEC | Proba | | | [UTC] | [UTC] | [deg] | [deg] | [%] | |-------------+------------+------------+---------+---------+---------| | FRAM-CTA-N | 2020-02-19 | 2020-02-19 | 189.377 | 55.273 |
