The Parity-Odd TB Spectrum Implied by a Uniform Rotation: A Cross-Check That Uses Temperature Instead of B-Mode Power

This paper examines what TB correlation a uniform rotation predicts, and whether TB offers an independent route to the same angle that does not depend on the much weaker B-mode signal in the same way EB does. The calculation is performed from stated assumptions and published polarisation measurements, using the deposited script so that every quoted number can be reproduced. The headline outputs are: beta deg = 0.30; TB uK2 = -0.314; mixing pct = 1.05; TE uK2 = -30.0. The treatment separates what the published measurements supply from what a theoretical framework must additionally provide; where a required quantity is not supplied, that absence is reported plainly as a negative result rather than replaced by an assumed value. The study is computed from stated assumptions and published inputs; it is not a new measurement. SIMULATED, NOT MEASURED in the sense that all derived quantities are calculated, not observed.
