EHT 2017 observing schedules for Sgr A* and its calibrators (J1924−2914 and NRAO530), covering observations on 2017 April 6–7. Open rectangles represent scans that were scheduled but not observed successfully owing to weather or technical issues. The filled rectangles represent scans corresponding to detections available in the final data set. Scan durations vary between 3 and 12 minutes, as reflected by the width of each rectangle. ALMA/APEX and JCMT/SMA are pairs of colocated stations (enclosed in light-blue shaded regions), providing the same (u, v)-coverage.
