No. It stands for "particles". Fluence is particles per cm2 (cmq unfortunately
is a leftover from Italian that should be corrected). Tracklength per cm3
is the the same thing as particles per cm2 (cm/cm3 = cm-2)

No, programs usxsuw, ustsuw etc. were written to analyze fluences (or currents).
They cannot know if the fluences are folded with conversion coefficients: there
is nothing in the *fort* files to indicate that.
Anyway, AUXSCORE was introduced later, ands the programs have not been modified.
