"body": "An error was introduced in the last circular on the absolute magnitude \ncorresponding to our observations of GW 150914. The absolute magnitude \nlimit is -19.6.\nBelow the corrected circular:\n\nA. Klotz (IRAP, CNRS/UPS), and M. Boer (ARTEMIS, CNRS/OCA/UNS) report on \nbehalf of the TZAC collaboration:\n\nWe have reduced and analysed the whole set of images acquired from \nTAROT-Chile (see LV GCN 18348, 18332 for the field coordinates and \nobserving log). Depending on the field, the final limits are between R \n >18.5 and 19.8. If we take a conservative limit of R> 18.5 at 2.8 days \nafter the GW event, this corresponds to an absolute magnitude of -19.6 \nat the distance of GW 150914."
