Notes.

(a)

RA, Dec are given in J2000.0;

(b)

Modified Julian Date of optical outburst; MJD = JD - 2 400 000.5;

(c)

Distance in arcsec between optical and X-ray source;

(d)

Time after observed start of optical outburst;

(e)

unabsorbed luminosity in 0.2–10.0 keV band assuming a 50 eV blackbody spectrum with Galactic foreground absorption, luminosity errors are 1σ, upper limits are 3σ;

(f)

SSS or SSS-HR indicate X-ray sources classified as supersoft based on XMM-Newton spectra or Chandra hardness ratios, respectively.
