VizieR Online Data Catalog: LIGO and Virgo third observing run with GRANDMA (Antier+, 2020)

The GRANDMA consortium presented in this paper, which is a global network of 21 telescopes with both photometric and spectroscopic facilities, located in 15 different observatories, aims to face the challenges of time-domain astronomy; in particular, it is set up for the case of large uncertainties in the localization of the transient phenomena as presented in Coughlin et al. (2019MNRAS.489.5775C). The network morphology has 24-h coverage and large availability of the telescopes, which helps to rapidly scan the GW sky localization area to ~18mag.

The GRANDMA consortium followed up 27/33 alerts during the first six months of the O3 campaign, as shown in Table 3 for the BBH merger candidates and Table 4 for the systems containing at least one neutron star based on LIGO-Virgo low-latency results. Links to all the sky localizations of the alerts are given in Table A1.
