Stellar populations in the Calán-ESO catalogue. The luminosity function and kinematics of dwarfs
Abstract
From the CALÁN-ESO (CE) catalogue limited in proper motion μ ≥ 0.2^-1 and aparent magnitude m^R ≲ 19.5 mag (Ruiz et al. 2001a), we studied the luminosity function (LF) with its errors in different galactic latitude and longitude for 14 areas distributed on the sky using Monte Carlo simulations to determine if there are variations in the LF for each zone. Also we studied the kinematics of diferent coexistent populations by fitting kinematical parameters of the distribution function of stars on the distance.
