[Mesa-users] [EXT] custom write photos

[Mathieu Renzo]

Hi Amadeusz,

Have you tried calling the function `star_write_photo` defined in 
`$MESA_DIR/star/public/star_lib.def`?
That should be straightforward from run_star/binary_extras.f90, and I 
have used it in the past (but can't find a snippet at the moment)
