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

Calculate the vertically-integrated surface density.

Parameters:

  • R (float or Quantity) – Galactocentric radius.

  • nz (int, optional) – Number of zs to use to estimate. Default is 7.

  • zmax (float or Quantity, optional) – Maximum z to use. Default is 1.0.

  • fixed_quad (bool, optional) – If True (default), use Gauss-Legendre integration.

  • fixed_order (int, optional) – Order of GL integration to use. Default is 8.

  • **kwargs (dict) – Density kwargs.

Returns:

Surface density at R.

Return type:

float or Quantity
