Notes.

^(a)

RA, Dec are given in J2000.0;

^(b)

Modified Julian Date; MJD = JD - 2 400 000.5;

^(c)

mrg (HRC-I/EPIC) indicates the merged data of all HRC-I/EPIC observations of the monitoring;

^(d)

Time after observed start of optical outburst;

^(e)

unabsorbed 3σ upper limits in 0.2–10.0 keV band assuming a 50 eV blackbody spectrum with Galactic foreground absorption.
