Over the past couple of weeks, I took transfer functions for SR3 and PR3 with different configurations of P or Y damping gain for the estimator, so here are the results for those plus a comparison of their peak locations.

SR3
DAMP P gain at -0.1 (nominally -0.5), other dof gains at their nominal -0.5
Measurements: 86203

DAMP Y gain at -0.1 (nominally -0.5), other dof gains at their nominal -0.5
Measurements: 86202
