    117117Models that do not conform to these requirements will *never* be incorporated 
    118118into the built-in library.

    120 More complete documentation for the sasmodels package can be found at 
    121 `<http://www.sasview.org/sasmodels>`_. In particular, 
    122 `<http://www.sasview.org/sasmodels/api/generate.html#module-sasmodels.generate>`_ 
    123 describes the structure of a model.

    614609    sas_gamma(x): 
    615         Gamma function $\text{sas_gamma}(x) = \Gamma(x)$. 
     610        Gamma function sas_gamma\ $(x) = \Gamma(x)$. 
    616611 
    617612        The standard math function, tgamma(x) is unstable for $x < 1$ 
     
    623618    sas_erf(x), sas_erfc(x): 
    624619        Error function 
    625         $\text{sas_erf}(x) = \frac{2}{\sqrt\pi}\int_0^x e^{-t^2}\,dt$ 
     620        sas_erf\ $(x) = \frac{2}{\sqrt\pi}\int_0^x e^{-t^2}\,dt$ 
    626621        and complementary error function 
    627         $\text{sas_erfc}(x) = \frac{2}{\sqrt\pi}\int_x^{\infty} e^{-t^2}\,dt$. 
     622        sas_erfc\ $(x) = \frac{2}{\sqrt\pi}\int_x^{\infty} e^{-t^2}\,dt$. 
    628623 
    629624        The standard math functions erf(x) and erfc(x) are slower and broken 
     
    634629 
    635630    sas_J0(x): 
    636         Bessel function of the first kind $\text{sas_J0}(x)=J_0(x)$ where 
     631        Bessel function of the first kind sas_J0\ $(x)=J_0(x)$ where 
    637632        $J_0(x) = \frac{1}{\pi}\int_0^\pi \cos(x\sin(\tau))\,d\tau$.

    657         If $n$ = 0 or 1, it uses sas_J0(x) or sas_J1(x), respectively. 
     652        If $n$ = 0 or 1, it uses sas_J0($x$) or sas_J1($x$), respectively. 
    658653 
    659654        The standard math function jn(n, x) is not available on all platforms.
