New reduction of photometric B, V, I observations from Stetson et al. (2003, Cat. J/PASP/115/413) with updated photometry zero-points according to Stetson et al...
UBVRI photometry of stars in Berkeley 86 (Deeg+, 1996)
Based on photometry of deep CCD frames of the central region of the OB cluster Berkeley 86, we derive the cluster mass function. The absence of current star...
Data on linear optical polarimetry were obtained during two observing runs at the Complejo Astronomico El Leoncito (CASLEO) in San Juan, Argentina, in 2003...
