Each tile is 1.9x1.9 degrees. These observations\ncover about 17% of the cumulative probability of the skymap.\n\nThe typical limiting magnitude is 18.0 for a 60.0 s exposure.\n\nThe coverage map is available at:\nhttps://grandma-owncloud.lal.in2p3.fr/index.php/s/9MO62YiDroG6GU6\n\nAccording to our data analysis, no serious optical transient candidates\nwere found.\n\nGRANDMA (Global Rapid Advanced Network Devoted to the Multi-messenger\nAddicts) is a network of robotic telescopes connected all over the\nworld with both photometry and spectrometry capabilities for Time-\ndomain Astronomy (https://grandma.lal.in2p3.fr/).
