Determining orbits from radial velocities

Determining orbits from radial velocities. Observe system over n times (observations) n observations n (V r , t) V = F(K,e, w,g ,T,P) since T,P enter expression for V via q , from time of observation t, estimates or known values of P,e,T, hence E (ecc. anomoly) Thus:
