[Mesa-users] Limiting the final radius of a simulation

 I want to stop several different MESA runs at the same final
(photospheric) radius (with a certain precision), but since the physics is
slightly different in each, I can't stop at the exact same radius. I
realize that one could decrease the timesteps of evolution to achieve this,
but was wondering if there is an easier way to achieve this.

I am already using the stop to limit the photospheric radius command, but
it always stops with a certain precision.

What I want is a way to tell the code to stop when the photosphere reaches
7+-0.01 solar radii , is there any command that could achieve that? I
tried delta_lgR_limit,
but I don't think that does what I have in my mind.
