VizieR Online Data Catalog: Hogg 16 peculiar stars (Cariddi+, 2018)

The photometric observations of Hogg 16 were performed on 2004 June 15, with the EFOSC2 instrument, installed on the 3.6m telescope at ESO - La Silla within the program 073.C-0144(A), and the target field was centred on the main concentration of stars in the cluster area (J2000 RA=13:29:18, DE=-61:12:00). The field-of-view is about 5.2'x5.2', and the 2x2 binning mode results in a resolution of 0.31"/pixel. Thus, we cover almost the complete cluster area if adopting a diameter of 6' as listed in the updated open cluster catalogue by Dias et al. (2002, version 3.5, Cat. B/ocl). We used a Δa filter set with the following characteristics: g1 (λc=5007Å, FWHM=126Å, TP=78%), g2 (5199, 95, 68), and y (5466, 108, 70).
We have investigated 150 stars in the area of the young open cluster Hogg 16 using the Delta-a photometric system. We have performed a membership analysis and identified several chemically peculiar cluster stars.
