What do the extra text fields in the Wavemon scan screen mean?

[Swamp Thing]

In the <F3> (scan) screen of Wavemon, there are certain outputs whose meaning I would like to know.

1. In the third column, there is a percentage. What does that indicate?

2. After the frequency column, some rows (i.e. some SSIDs) have extra text fields like "ESS", "5% chan", "1 sta", "Radio Measure", "Spectrum mgmt".

6, 2437 MHz 1 sta, 3% chan, Radio Measure, Spectrum Mgmt

What do those extra items mean? The MAN page does not explain this, nor could I find other sources of information.

It's an informative video, but it doesn't explain those extra text fields in the scan screen.
