+The naming of output files in legacy Beta-Beat.src analysis can be very unintuitive.
 Namely, one will see similar output files for a quantity which go as `get_*.out`, `get_*_free.out` and `get_*_free2.out`, where `*` is the calculated quantity (betas, phase, etc.).
 These each correspond to a variation of the calculated quantity, explained below.

-    In the case of the `get_*_free2.out` files, the compensation is done differently depending on the computed quantity.
-    For some quantities (for instance for $\beta$ from phase) this uses the model values, for others (for instance the coupling RDTs $f_{1001}$ and $f_{1010}$) it is a rescaling in which the model values are used *indirectly*.

 The method used to output the `get_*_free2.out` files is sometimes more robust as it does not rely on the existence of certain BPMs in the output (which could be missing after cleaning), and in some edge cases is more accurate[^HoydalsvikSubPerMilCouplingLHC].
