VizieR Online Data Catalog: Open cluster Pis 20 (Vazquez+, 1995)
Abstract
The very young open cluster Pis 20 has been investigated using CCD UBVR photometry. New blue faint members were found down to V=19mag. With them we obtain a better definition of the lower cluster main sequence. Using the fitting method, we derive a cluster distance of d=3600pc (V0-MV=12.80). The mean color excess is <EB-V>=1.24mag.
