In plain words A library keeps three lists: what was delivered, what was catalogued, and who checked it out. A measurement corpus needs the same three, and a gap between them is a fact about the pipeline, not about the room. This is the ledger, per day and receiver, with every session as a row you can open.

The rate ladder

Counts and yields

Records	188,573
Frames the radio saw	191,820
Empty records	5,710
useful_yield	0.9533
capture_yield	0.9831
Empty share	0.0303
Mean rate	129.8 Hz
Bytes	132,003,276
Band / channel / width	5 GHz / 48 / HT20

Quote useful_yield: (records − empty records) ÷ frames the radio saw. capture_yield counts an all-zero record as delivered. A low capture_yield on 2.4 GHz is DSSS/CCK traffic that yields no channel estimate, not a quiet channel. Both are derived ratios from two independent counters and exceed 1.0 on some sessions; the counts are exact, the ratios are not.

Record classes

What the channel carried, by tone count and modulation. A bandwidth is printed only when every frame of the class named the same one.
