- "This parameter is also known as the number of \"streams\" in the radiation literature and in Stamnes' DISORT [[3]](#cite-Sta1999). We require an even $\\text{NQuad} \\geq 2$. This parameter incurs the largest computational cost in `pydisort`, with scaling like $\\mathcal{O}\\left(\\text{NQuad}^3\\right)$. An excessive number of streams will cause numerical instability: if $\\text{NQuad} \\gtrsim 300$ some quadrature angles will be extremely glancing ($\\mu \\sim 0$) and the computed intensity at those angles will be inaccurate."
