Abstract
The open star clusters M36, M38 and NGC 2477 were investigated by the strip method on charts of photographs taken with the Schmidt-Spiegel of the German Observatory Hoher List (M36/38) and the Curtis-Schmidt Telescope of the Cerro Tololo Interamerican Observatory (NGC 2477). The results are â Masses: 830, 2350, 4400\(\mathfrak{M}_ \odot\); radii: 6.4, 10.0, 10.0 pc; central densities: 9.9, 15.3, 32.5\(\mathfrak{M}_ \odot\) pcâ3; density laws: Gaussian (M36), generalized law of Schuster withn=3.00, 2.79; mean velocities of the stars 0.74, 1.01, 1.38 km sâ1.
