[ConTeXt] math eq align

[Tobias Burnus <burnus@gmx.de>]

Hi,

since we have some TeX and math experts on the list, how can I best align this:

{\omega_1 =\omega_0=\omega_{\rm s}}               {Z_1=\pmatrix{1\cr1\cr}={\bi
Z}_{\rm s}} \formulenumber{a}
{\omega_2 =-\omega_0=-\omega_{\rm s}}             {Z_1=\pmatrix{1\cr1\cr}={\bi
Z}_{\rm s}} \subformulenumber{b}
{\omega_3 =\omega_0\sqrt{1+2f}=\omega_{\rm a}}    {Z_1=\pmatrix{1\cr-1\cr}={\bi
Z}_{\rm a}}\subformulenumber{c}
{\omega_4 =-\omega_0\sqrt{1+2f}=-\omega_{\rm a}}  {Z_1=\pmatrix{1\cr-1\cr}={\bi
Z}_{\rm a}}\subformulenumber{d}

Regards,

Tobias
