We consider a static and axially symmetric metric containing two quadrupoleparameters. In the present contribution, we study the quadrupole momentsconstraints on the properties of the relativistic accretion disc models, alsoexplore the relation of oscillatory frequencies of charged particles to thefrequencies of the twin high-frequency quasi-periodic oscillations observed insome microquasars. We also compare the results with Schwarzschild and Kerrmetrics.
