ULA Vulcan Launch Vehicle (as announced/built) - General Discussion Thread 3

[newalex]

Today I've become interested in comparison of internal useful volume for different launches. I came to Vulcan User's Guide for info.  And there is the following interesting image(attached)
I have a problem with understanding what LV STA means. It seems to be something in inches(although I am not sure) and LV is definitely stands for launch vehicle. Maybe somebody know what STA there means?

STA is probably Station. It is the distance from a fixed reference point (probably something at the bottom).

I think it is structural test artical.

Yes.  Station in inches or millimeters from a reference point that usually is even with the bottom of the core vehicle, sometimes at the base of the thrust chambers, other times at the base of the structure, etc., although in the early days of missiles the reference point was usually at the top of the standard RV and the numbers grew in value downward.

Thanks everyone for the answers! Especially Ed Kyle for such details. So I think it's safe to assume those values are really in inches.
