Notes. (a)1.3 mm dust continuum flux density with the fragment after subtracting the contribution from free-free emission (see Section 4.3). (b)Effective radii of the fragments 
(see Section 3.1). (c)Position angle for identified CO outflow axis. (*) indicates the orientation of the unipolar CO outflow associated with the fragment. (d)Position angle of velocity gradient (the direction of increasing velocity, measured east of north) detected in CH3CN (123 − 113) emission. “…” means no clear velocity gradients were detected. (e)Fitting results of CH3CN emission average over the region of identified fragments in Section 4.3. (f)The central enclosed mass by fitting the Keplerian profile to the PV diagram of CH3CN (123 − 113) using KeplerFit.
