\caption{\label{HH52vrad1:tab}Radial velocities and line intensities for different optical lines of individual knots in HH~52 from EMMI and B\&C~spectra. Radial velocities are corrected for the cloud speed with respect to the~LSR ($v_{\rm LSR}$~= 2~km~s$^{-1}$, Knee \cite{knee}). When detected, two velocity components are reported.}
