  The subscripts associated with sources 3, 11 and 14 correspond to two different velocity components required for the spectral fits.\\
  $^a$ The offsets are given with respect to the phase center  RA[J2000] 
  19$^{\rm h}$19$^{\rm m}$50.169$^{\rm s}$ and Dec[J2000] 14$^{\circ}$01$'$13.75$''$.\\
  $^b$ The virial masses were calculated following
  \citet{maclaren1988} for $1/r$ and $1/r^2$ density distributions,
  resulting in the ranges of values. All source radii were
  approximated with half of the average N$_2$H$^+$ synthesized beam
  of $\sim $$3.1''$. Only for peak one we used a source radius of
  $3.5''$.
