We built on the templates set by the PR3 L/P estimator blends [see LHO: 87596] to create Length and Pitch blend filters for the SR3 OSEM estimator.
The functions that make the model and OSEM filters live in:
blend_SR3_lengthv2_LP_est.m
blend_SR3_pitchv2_LP_est.m
The files were committed to the SVN at (svnRoot)/sus/trunk/HLTS/Common/FilterDesign/Estimator/ under revision 12741.
make_EST_blends.m in the same folder should work for getting these onto the real-time model.
