Mass function of the YSO candidates in each cluster. The full well-fit lists are under the thick black line. Top lines show the Kroupa IMF. The shaded portion indicates α-selected sources. a) N11: total mass of all 242 well-fit sources is 1391  ±  26   M_⊙ with mass from integrated Kroupa IMF  ~ 4905   M_⊙. b) N44: mass of 139 well-fit sources: 900  ±  25   M_⊙; from integrated Kroupa IMF  ~ 3537   M_⊙. c) N51: mass of 103 well-fit sources: 557  ±  17   M_⊙; from integrated Kroupa IMF  ~ 2339   M_⊙. d) N105: mass of 91 well-fit sources: 526  ±  14   M_⊙; from integrated Kroupa IMF  ~ 2539   M_⊙. e) N113: mass of 101 well-fit sources: 586  ±  15   M_⊙; from integrated Kroupa IMF  ~ 3157   M_⊙. f) N120: mass of 51 well-fit sources: 291  ±  10   M_⊙; from integrated Kroupa IMF  ~ 998   M_⊙. g) N144: mass of 31 well-fit sources: 163  ±  8   M_⊙; from integrated Kroupa IMF  ~ 879   M_⊙. h) N160: mass of 214 well-fit sources: 1424  ±  24   M_⊙; from integrated Kroupa IMF  ~ 6841   M_⊙. i) N206: mass of 73 well-fit sources: 431  ±  12   M_⊙; from integrated Kroupa IMF  ~ 2088   M_⊙.
