quasiisothermaldf.surfacemass_z(R, nz=7, zmax=1.0, fixed_quad=True, fixed_order=8, **kwargs)

NAME:

surfacemass_z

PURPOSE:

calculate the vertically-integrated surface density

INPUT:

R - Galactocentric radius

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=m minimum z to use

density kwargs

OUTPUT:

Sigma(R)
