According to this article, the data format is:

\(voltage_1\) Pport1mode1 Pport1mode2 Pport2mode1 Pport2mode2 \(f_1\) abs(s) angle(S) 
for 1by1 port2 with 2by2 modes.

abs(s) means the absolute value of s parameter.
Pport... means the power.

The intensity varying absroption is embeded inside the s parameters with certain algorithms, which is not open to public.

My colleague may comment for more.
