Notes.V0 − MV are the individual values for stars with spectral data, but the adopted cluster values (see Table 1) for stars with only photometric information.

(•)

Indicates adopted no cluster member stars.

(a)

SpT = o5v assigned by Roman-Lopes & Abraham (2004)-IRS1; not considered when calculating the mechanical energy of the DBS 160−161 cluster (see Sect. 5.1).

(b)

Considered O9.5 V spectroscopic spectral type according to Roman-Lopes et al. (2009)-IRS3 to calculate the mechanical energy (see Sect. 5.1).

(c)

SpT asigned by Roman-Lopes & Abraham (2004).
