    10:20/17:20      CAGIRE Performances (20+5) Nouvel de la Flèche

CAGIRE is the near infra-red camera of the Colibrí robotic telescope. It is based on the ALFA 2k x 2k detector from the Lynred French Company operating in “Ramp” mode. An observation consists of a series of short (1-2 minutes) exposures during which the pixels are read out every 1.3 second, while they continuously accumulate charges proportionally to the flux they receive. We discuss here the methods that can be used to recover the flux received by each pixel from the slope of the ramp.

    10:50/17:50      DDOTI Observations of Gravitational-Wave Sources Discovered in O3 (15+5) Rosa Becerra

We present optical follow-up observations with the DDOTI telescope of gravitational-wave events detected during the Advanced LIGO and Advanced Virgo O3 observing run. We compare our upper limits to various possible counterparts: the kilonova AT~2017gfo, models of radioactive- and magnetar-powered kilonovae, short gamma-ray burst afterglows, and AGN flares.
