[Mesa-users] Gravity Darkening

Hi Alvaro,

Please find attached a version of run_star_extras.f that will include the
inclination angles i=30 and i=60 degrees.  This was tested with 11701 but
should also work with 12115.

See the functions how_many_extra_history_columns and
data_for_extra_history_columns.  The former sets the value to 4 and the
latter populates those 4 extra columns with data.

I have tried this run_star_extras with the mesa test_suite case
high_rot_darkening.  That test was made to highlight the capabilities in
section 4 of MESA 5.  It already includes the polar (i=90 degress) and
equatorial (i=0) and so you can check it to verify that the reported Teff
and L values at 30 and 60 degrees lie between the values at the equator and

Let us know if you have any questions.
