Notes:
The information on $v\sin i$ values, mass-accretion rate, IR features, binarity, effective temperature,
luminosity, and age was collected from the literature. 
The mass was deduced from the position of the star in the H-R diagram (see Sect.~\ref{sect:link}).
Objects marked with $^*$ are excluded from the correlation analysis
(see Sects.~\ref{sect:observations}, \ref{sect:prev_detect}, 
and~\ref{subsect:accr_rate}).\\
