The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We introduce novel applications for the monitor and derive a new method for calculating the effect of gain drift on integrated data.

C2weakest assumption

The commissioning improvements in calibration method, analog section temperature, and gain stability are assumed to be sufficient to enable reliable long-term operation and accurate transient detection without introducing new systematic errors.

C3one line summary

A 2 GHz bandwidth RFI monitor was commissioned at DRAO for transient detection and radio environment characterization, with a new method derived for calculating gain drift effects on integrated data.
