Central instant: results of the mutual approximation campaign for 2017 and 2018. Note that 501 stands for Io, 502 for Europa, 503 for Ganymede and 504 for Callisto. σt0 is the central instant error in seconds of time and in mas (using the relative velocity in each event obtained with the ephemeris) and Δt is the comparison between the observation and the ephemeris JUP310 (with DE435) from the JPL in the sense of observation minus ephemeris in seconds of time and in mas. N is a sequential number with time that labels each observed mutual approximation. Time is utc.
