TITLE: GCN CIRCULAR NUMBER: 19048 SUBJECT: LVC GW 150914: TAROT/TZAC Final analysis DATE: 16/02/22 10:07:11 GMT FROM: Michel Boer at CESR-CNRS A. Klotz (IRAP, CNRS/UPS), and M. Boer (ARTEMIS, CNRS/OCA/UNS) report on behalf of the TZAC collaboration: We have reduced and analysed the whole set of images acquired from TAROT-Chile (see LV GCN 18348, 18332 for the field coordinates and observing log). Depending on the field, the final limits are between R >18.5 and 19.8. If we take a conservative limit of R> 18.5 at 2.8 days after the GW event, this corresponds to an absolute magnitude of 19.6 at the distance of GW 150914.
