[NTG-context] Math fonts for Nimbus fonts

[Otared Kavian]

Hi,

I wish to use the Nimbus fonts, but since I didn't know which Math fonts is best adapted to this family, I tried several fonts such as Stix Math, TeX Gyre Math, and so on, but doing this the math-italic does not appear in these fonts: does this mean that I have to set explicitely math-italic in definefontfamily?

Also what is the best math font adapted for Nimbus?

Below is my definition of a fontfamily for Nimbus fonts.

Thanks in advance for any help: Otared K

%% begin definefontfamily-nimbus.tex
\definefontfamily [mainface] [rm] [Nimbus Roman No9 L]
\definefontfamily [mainface] [ss] [Nimbus Sans L] [rscale=0.85]
\definefontfamily [mainface] [tt] [Nimbus Mono] [features=none,rscale=0.95]
\definefontfamily [mainface] [mm] [STIX Math]

%\definefontfamily [mainface] [mm] [Asana Math]
%\definefontfamily [mainface] [mm] [Lucida Bright Math OT]
%\definefontfamily [mainface] [mm] [TeX Gyre Termes Math]
%\definefontfamily [mainface] [mm] [XITSMath]

\setupmathematics[integral=nolimits,lcgreek=normal,default=normal]


\setupbodyfont[mainface]

\starttext

{\rm\tf Regular \it Italic \bf Bold \bi BoldItalic}

{\ss\tf Regular \it Italic \bf Bold \bi BoldItalic}

{\tt\tf Regular \it Italic \bf Bold \bi BoldItalic}

And here are a few math formulas $\alpha^2 + \beta^2 + \gamma^2 = x^2 + y^2 + t^2$.
\startformula
\int_{0}^{2\pi} \sin(x)dx = 0, 
\qquad {\rm e}^{{\rm i}\pi} + 1 = 0, 
\qquad \sum_{n=1}^{\infty}{1 \over n^2} = {\pi^2 \over 6}.
