Table 5

Radial velocities v_rad obtained from the available emission lines, corrected for the systemic velocity of the cloud core of v_LSR = 8 km s^-1, and the number of lines used to measure v_rad.

Object	v _rad	N _lines	v _tan	v _space
	(km s^-1)		(km s^-1)	(km s^-1)

MHO2234-A1+A2^*	–32 ± 7	4	121 ± 12	125 ± 14
MHO2234-D1+D2	0 ± 4	4	110 ± 12	110 ± 13
MHO2234-H1	–12 ± 8	4	71 ± 12	72 ± 14
MHO2234-J	16 ± 1	2	n.a.	n.a.

MHO2235-B	5 ± 3	5	26 ± 12	26 ± 12

Notes.The tangential velocities v_tan were obtained from the proper motion measurements over 10 years and a distance assumption of d = 415 pc. The space velocities v_space were obtained by combining v_rad and v_tan.

^(*)

Both knots are included in the slit, but v_space is only valid for A2.
