Scientific paper

A detailed isotropic model is applied to the bulge of the lenticular galaxy NGC 7814, using photometric data from Van der Kruit and Searle (1982) and kinematic data from Kormendy and Illingworth (1982). This model gives a good fit of all the 103 observed velocities and velocity dispersions. The only free parameter of this model is the blue mass-to-light ratio, found to be 7 in solar units.
