[mesa-users] run gyre only

Fri Jan 20 13:03:36 EST 2017

Hi Rich,

Like to double check one thing please :-) Are the xi_r and xi_h in the
output mode file consistent with the following formula please? I define er,
etheta, and ephi as the normal vectors along r, theta, and phi directions
in a spherical coordiantes, and Y_{lm} is the normalized spherical harmonic.

xi (vector) = xi_r *Y_{lm}*er + xi_h *({\partial Y_{lm} \over \partial
theta}*etheta + 1/sin(theta)*{\partial Y_{lm} \over \partial\phi}*ephi

Although this is the conventional definition, I still like to make it sure,
many thanks [image: :-D]

Sincerely,
Jing
