Since my last "call for help" for the Jacobian had a great response rate, I thought perhaps I seek help again from this group, this time for a question that I am stuck with for the past month. (I have already emailed the theorists, but I know there must be
similar talent in this group to help me at a level closer to an experimentalist's).

I have been trying to figure out how to derive the target-mass correction (TMC) terms for PVDIS asymmetries. The results were given in

What I would like to do is to understand how these results were obtained so I can extend it to a new set of asymmetries I am working on. I have attached a short writeup. The question is posed on page 4, with pages 1-3 intro to the observables and page 5-7
references.</div>

I am wondering if anyone can help with this? I don't need the exact derivation step by step, but rather instructions for how to do so (and I can deal with the algebra, or find someone to do it).</div>
