From the calibration and measurement results of full one-port measurements
of the reflection coefficient of a constructed experimental one-port black box,
we concluded by trial-and-error that, as it seems, the 1st line from below in p.1
of "NanoVNA Console Commands 8-6-19.pdf", that is this one:
"NOTE: need to determine what the output parameters above represent."
which is referenced to the Console Command "data", is redundant, at least in
this case, because, the values in the two 2 columns are - from left to right -
the Real part and the Imaginary part, respectively, of the reflection coefficient.
