Covariance matrix of I, Q, U
Redundancy together with angular homogeneity impact on the S/N + IQU decorrelation
An intuitive estimator of the quality of the pointing is
Scanning strategy is the first tool for systematic mitigation

Trajectory of one pixel on the sky
Example of set of parameters:
T = 43200 sec
T = 2400 sec
T = 20 sec
At this stage of the study, we did not have to quantify exactly the benefit from a particular set of parameters. But we did find one that is feasible and meets the constraints we set.
