[CIG-SEISMO] SPECFEM2D Moment tensor

Dear SPECFEM2D developers and users,

I would like to ask for your help on how to make a proper approximation on
a station using a moment tensor as a source.

I ve gone through the manual and the relative papers describing the problem
but I got  a little bit confused.

So if I have for example a Strike 322, Dip 40, Rake -72 foc mec
then I get

Mxx  Myy  Mzz  Mxy  Mxz  Myz :
0.54774   0.38886  -0.93661   0.50245  -0.28821   0.01560

If I use only Mxx Mzz Mxz its fine for the stations at distances bigger
than the dimensions of the rapture. BUT only for the stations with 90deg

In practice, how can I get the correct Mxx Mzz Mxz at a station with a
different azimuth? Lets say 60 deg.

Can you please provide an example on that? I am interested for P waves for

Thank you in advance, your help means a lot
