sigmaT2
(R, romberg=False, nsigma=None, phi=0.0)¶ NAME:
sigmaT2PURPOSE:
calculate sigma_T^2 at R by marginalizing over velocityINPUT:
R - radius at which to calculate sigma_T^2 (can be Quantity)OPTIONAL INPUT:
nsigma - number of sigma to integrate the velocities overKEYWORDS:
romberg - if True, use a romberg integrator (default: False)OUTPUT:
