surfacemass_z
(R, nz=7, zmax=1.0, fixed_quad=True, fixed_order=8, **kwargs)¶ NAME:
surfacemass_zPURPOSE:
calculate the vertically-integrated surface densityINPUT:
R - Galactocentric radius (can be Quantity)
fixed_quad= if True (default), use Gauss-Legendre integration
fixed_order= (20), order of GL integration to use
nz= number of zs to use to estimate
zmax= maximum z to use (can be Quantity)
density kwargs
