#42 : The compact SLO formula for [AnyVNA]

Hello,

Allow us, please, to inform you that our two final reports:

1 : #30 : 5 October 2019 : https://groups.io/g/nanovna-users/message/4179
https://www.op4.eu/code/ref2007box/r.ref2007box.blue.vna.red.nanovna.c.gza.cc.by.4.0.png
https://www.op4.eu/code/ref2007box/x.ref2007box.blue.vna.red.nanovna.c.gza.cc.by.4.0.png

2 : #38 : https://groups.io/g/nanovna-users/message/4293

https://www.op4.eu/code/ref2007box/x.box.nanovna.deis.c.gza.cc.by.4.0.png

are resulted after we used the formulas given at:

#16 : 27 September 2019 : https://groups.io/g/nanovna-users/message/3161
https://www.op4.eu/code/cc-by-4.0-gz-ain-vna-params.png

with the clarifications provided at:
#17 : 27 September 2019 : https://groups.io/g/nanovna-users/message/3192

for the following Nominal Values of SLO "standards":

Short : A := S = Polar : ( 1 , 180 ) = Cartesian : ( -1 , 0 ) = Complex : -1 + j0 = Real : -1
Load : B : = L = Polar : ( 0, undefined) = Cartesian : ( 0, 0 ) = Complex : 0 + j0 = Real : 0
Open : C := O : Polar : (1 , 0) = Cartesian : ( 1 , 0) = Complex : 1 + j0 = Real : +1

and the following Indicated values of our [NanoVNA]
and [VNA]

Short Indication : a := s
Load Indication : b := l
Open Indication : c := o
Unknown load Indication : gamma

substituted to:

to got the following minimal mathematical expression
for the Unknown Gamma measured by [AnyVNA] - all complex:

at each defined frequency.
