jeanspy.model.DSphModel.sigmat2

Class and construction: DSphModel.

DSphModel.sigmat2(r_pc)[source]#

Return the tangential velocity dispersion squared at r_pc.

Notes

Inputs and units. r_pc is a scalar or NumPy array of positive intrinsic radii in pc.

Returns and shape. Variance in (km/s)^2, following input shape; scalar input is a zero-dimensional NumPy array.

Validity. Uses adaptive integration to infinite radius with vanishing outer pressure. The intrinsic helpers do not apply all LOS input validation checks.
