jeanspy.model.DSphModel.sigmalos

Class and construction: DSphModel.

DSphModel.sigmalos(R_pc, n=1024, n_kernel=128, ignore_RuntimeWarning=True, *, method='dequad')[source]#

Return the LOS velocity dispersion in km/s.

Accepts the same radii, integration method and numerical controls as sigmalos2() and returns its square root. The result is scalar for scalar input, otherwise shape (N,). method="dequad" is the default and currently the only supported choice. The same validity checks and errors apply. This is a NumPy/SciPy calculation without JAX tracing.
