Difference between some dc parameters on spectre user manual

Hello,

I am looking at the spectre user manual for IC6.1 and I see the following parameters:

u: transistor gain no unit given

self-gain: transistor gain with no unit given

fug: unity gain frequency at actual bias in Hz

ft: unity gain frequency at actual bias in Hz

These are given on page 2106 for PSP103 model which I am using. 

I know that in some literature ft which stands for the transit or transition frequency is ten times the fug (unity-gain frequency). How about they and self-gain? Do they mean the same thing?

My Virtuoso version is:

Version IC6.1.8-64b.500.9

Spectre191

Thank you very much in advance.
