Perseus	126	0.64	11229	− 3.190 ± 0.033	0.6

Notes. N: number of protostars (126 instead of 132 for whole Perseus because for six protostars the column density could not be computed, see text); N(H₂): minimum background column density in 10²¹ cm⁻²; M: mass in M_⊙ for N(H₂) > min; s slope of PDF; SFE in %.
