Abstract
A systematic photometric investigation on stars of spectral type G4toK4is performed in both polar caps insymmetric coaxialcones. According to a calibration of the Geneva system, Mv, Teff and [M/H] ratio have been now derived for about 4OO stars. For the computation of density law, a special care has been taken to avoid selection biaises related to variations of mean age or metal abundance. A change of luminosity function for evolved stars in function of z has been detected. Using the geometrical properties of the cones and direct counts in the solar vicinity, we derive the following density law for stars with Mv ∊ [0.0, 1.3] and (B-V) ∊ [0.7, 1.3]
