propagation_delay

Astrophysics.Pulsars.propagation_delay(electron_density, path_length, frequency)

EM radiation propagation time

Time-of-flight is calculated from physical parameters

:type electron_density : float :param electron_density : in cm^{-3}

:type path_length : float :param path_length : in pc

:type frequency : float :param frequency : in MHz

Returns

time in seconds
