[Mesa-users] jdot_scale warning - direct impact mass transfer in AM CVn binary

[Pablo Marchant]

Hi James,

doing a grep on the source code for that I found what I suspected that was.
It is just a leftover debug output within the function that computes
magnetic braking. You can safely ignore this, or if it bothers you too
much, make use of the other_jdot_mb to copy the functionality in
$MESA_DIR/binary/binary_jdot.f90 without the annoying bit.

Cheers
