LEAPR S(alpha,beta) and rho phonon frequency spectrum

[negatron1]

Hi everyone, hope everything is going well.
I am new to NJOY environment but ı made a bit of progress by using njoy16 and end102 documents. I encountered something that caused confusion to me while producing s(a,b) for thermal scattering.

Firstly;
To produce mf7 data for THERMR module, where can ı find alpha, beta and, rho phonon frequency spectrum values which are used by LEAPR to produce s(a,b) law? In fact, my aim is that finding mentioned data for not given temperatures. For example, I downloaded ENDF data for graphite which includes data for a few temperatures (296 400 500 600 700 800 1000 1200 1600 2000 K) but my target is a different temp like at 850 K. As given in the manual, values do not depend on temp for graphite meaning we can use them for other temperatures.; however, how about other moderators especially temperature is important, for instance, inelastic scatterings?

Secondly,
As ı understood, we have to produce s(a,b) law, which is necessary, in order to use it in thermr module and we create X section values for given materials at the desired temperature. If we already produced it while generating new X sections at the desired temperatures, why do we use s(a,b) again in the mcnp input file such as h2o at 650 K (h-h2o.56t)

hope my questions and explanations seem to you clear, looking forward to hearing from you.
best regards.
