[Clas12_rgb] RG-B e- Momentum Corrections

[Richard Tyson]

Hi all,

As discussed at the meeting today, I've been working on electron momentum corrections. These are available, see example C++ code below.

It would be great if other analysers could have a quick go at trying these out as the J/psi channel is maybe not the best suited for this due to low statistics.

 The slides are on the RG-B wiki<https://clasweb.jlab.org/wiki/images/b/b2/24_01_2025.pdf>, please let me know if you have any questions.

Cheers,
Richard
