snorer.get_vx

ssnorer.get_vx(Tx,mx)

Get dimensionless BDM velocity \(v_\chi/c\). See BDM Physics for detail.

Parameters:

Tx : array_like
    BDM kinetic energy \(T_\chi\), MeV

mx : array_like
    DM mass \(m_\chi\), MeV

Returns:

out : scalar/ndarray
    Dimensionless BDM velocity. out is scalar if all inputs are scalars.
