\caption{Average absorbed and unabsorbed X-ray luminosities of WR~25 for
the three missions {\it ROSAT}, \ASCA and {\it XMM-Newton}.  The absorbed
X-ray luminosity is derived from the X-ray fluxes (Table~6)
using the adopted distance of WR25.  The unabsorbed X-ray luminosity is the
X-ray luminosity of WR25 just outside the absorbing wind, thus only
corrected for interstellar absorption.
