Notes. 

(*)

SI: SHP97, SII: SHL2001

(+)

XID Flux and error in erg cm-2 s-1.

(†)

Variability factor and significance of variability, respectively, for comparisons of XMM-Newton XID fluxes to ROSAT fluxes listed in SPH97 and SHL2001, respectively.

(‡)

An asterisk indicates that the XID flux is higher than the corresponding ROSAT flux. ROSAT count rates are converted to 0.2–4.5 keV fluxes, using WebPIMMS and assuming a foreground absorption of NH  = 6.6  ×  1020 cm-2 and a photon index of Γ = 1.7: ECFSHP97 = 2.229 × 10-14 erg cm-2 cts-1 and ECFSHL2001 = 2.249 × 10-14 erg cm-2 cts-1.
