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	614,492
Frames the radio saw	1,038,875
Empty records	25,290
useful_yield	0.5672
capture_yield	0.5915
Empty share	0.0412
Mean rate	373.2 Hz
Bytes	430,144,400
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.
