\begin{table}%t3
\caption{List of all companions detected within 10\arcsec\ (Ophiuchus) or 30\arcsec\ (Taurus) of our
targets. Flux ratios are measured with respect to the
brightest component in the $K$~band image, except for three
systems where the Class~I source is the faintest component in
the near-infrared ($\dagger$~symbol). The boldfaced entries
represent systems that are likely to be physically bound (see
Sect.~\ref{subsec:bf}).  The two companions to IRS~54 listed in
italics were detected by combining a short and a long exposure
and are not included in our survey. Upper limits for flux
ratios are at the 3$\sigma$~level. IRAS~04264+2433 was
saturated in all of our images, so only a lower limit for the
flux ratio to its companion can be obtained.}\label{tab:bin}
