-function [psr_rad]=psr_vs_detuning(detuning_freq, Ep, psi_el, B_field, theta, phi) 
-% calculates psr in rad  vs detunings of the probe field 
-% for given laser probe and B field.
-% Probe field defined by field strength (Ep) and ellipticity angle (pse_el)
-% Magnetic field defined by magnitude (B_field) and angles theta and phi.

-% Note: it is expensive to recalculate atom property for each given B_field strength
