\caption{NIR/X-ray flare flux densities.
The peak flux densities of the flares detected in the individual 
wavelength bands are given.
The spectral index is calculated assuming band centers
of 2.2~$\mu$m and 1.6~$\mu$m in the near-infrared and 4~keV in the X-ray domain.
The X-ray flares~$\phi$2, $\phi$3 and $\phi$4 have been detected simultaneously in 
the NIR. For flare $\phi$1 only an upper limit in the $H$-band is available.
For flare~V no X-ray data exist.
See comments on the candidate X-ray flare events $\phi$1, $\phi$2, and $\phi$4
in the text and in in Table~\ref{flareprop}.
