EHT datasets on M87* This work uses the publicly available network-calibrated datasets of M87* (https://eventhorizontelescope.org/for-astronomers/data), reduced through the EHT-HOPS pipeline, on the basis of observations obtained in 2017 (ref. 2), 2018 (ref. 33) and 2021 (ref. 34). In 2017, EHT observations of M87* were conducted with seven separate facilities1: the Atacama Large Millimeter/submillimeter Array (ALMA)49,50, the Atacama Pathfinder
