Help with editing .asm files for P3D

[bentkj]

Hi everyone! I need some help digesting what is needed for my C-130 simulation and its .asm files.
Here's the background:

In a nutshell, I want to use CFD (ANSYS Fluent) to obtain aerodyanmic data to be used to build a .asm and eventually .air file for P3D.

I have a TurboPropSample.asm file which I got from online somewhere to edit
and the first block is the "required aerodynamics" section which is as below.
I would like to know what do the various terms in BOLD refer to and the numbers beside them mean?
I have a background in aeronautical engineering and am familiar with flight dynamics.
