a Maximum likelihood for detection for XMM-Newton data, CIAO WAVDETECT "Significance'' for Chandra data. b Variability flag: 0 = no or only low-level variability; 1 = clear flaring, flare intervals removed in spectral fit; 2 = clear flaring observed but flare intervals not removed; 3 = slow decay of flare throughout observation, all data used. Notes on individual objects:
  • CoKu Tau 1 = XEST-23-000: Chandra observation C1 may contain a marginal off-axis detection ($\approx$6 counts).
  • V892 Tau= XEST-23-047 = XEST-24-040: Companion at 4 $^{\prime \prime }$ is visible as a faint source in Chandra observation C1.
  • HP Tau/G2 and G3 = XEST-08-051 (separation: 10 $^{\prime \prime }$) were treated as one source. The ratios of the counts and rates were derived from PSF fitting in the image.
