The different photometric diagrams indicate the presence of three superimposed stellar groups, all composed of early type stars. Description: CCD UBV(RI)c imaging photometry was carried out in the field of Stock 16 along two observational runs at the University of Toronto Southern Observatory, Las Campanas, Chile, using the Hellen Sawyer Hogg 60-cm telescope: on the nights of 1994 April 13, 14 and 16, we obtained UBVRI photometry for four frames with the nitrogen-cooled detector PM METHACROME UV coated (0.45"/pix) covering 4' on a side; three more frames were exposed on the nights of 1996 February 25 and 26 in the UBV(I)c bands (this time, the detector was glycol-refrigerated).

Note (1): Note on rms uncertainties: e_Vmag, e_B-V, e_U-B, e_V-R and e_V-I were obtained by quadratically adding transformation and internal errors to the DAOPHOT ones. See the article. Note (2): Membership assignations are abbreviated as follows: m = member pms = probable pre-main sequence star; the corrected (B-V)0 was obtained using the mean E(B-V) pms? = probable member below the ZAMS or probable pre-main sequence star pnm = probable non-member A = star in Group A B = star in Group B
