Azz is an asymmetry so take advantage of numerator denominator systematics cancellation:<\br>

1.) Measure Np and Nu with same cup same exact material<\br> 2.) Use same B-field<\br> 3.) Use NMR on both to measure polarization and un-polarization<\br> 4.) Let beam heating an off larmor microwave control un-polarization<\br> 5.) Keep both cold (~1K)<\br> 6.) Switch from pol to unpol frequently<\br>
