Class and construction: AxisymmetricDSphModel.

AxisymmetricDSphModel.jfactor(dist_pc, roi_deg, *, params=None, **quadrature)[source]#

Postprocess an axisymmetric finite-cone factor.

Notes

Inputs and units. Scalar dist_pc and roi_deg; params specifies halo, inclination and finite r_t_pc; n_mu/n_phi/n_radial set independent factor quadratures, all >=16.

Returns and shape. Python float in GeV^2 cm^-5.

Validity. Require explicit finite r_t_pc, observer distance > r_t_pc*max(1,Q), 0 <= roi_deg < 90 and gamma<1.5 (finite central annihilation integral). n_phi uses a periodic rule; refine all orders.
