simon, tracking meeting presentation, does not look like we need the half-cell offset. chisq distributions look similar eugene, result may depend on starting point, may induce ambiguity mis-resolution can throw with correct parameter, not using standard candidate finding (helical fit). Explanation of finding and fitting

???do the other layers in the default geometry help resolve l-r in a given layer???MMI answer is yes

???kalman filter reference???

poisson: some maps generated, 4x # points tried successfully along beam line discreprency with ansys compare field directly run more simulations compare resolutions

beni: structural elements in cdc have been added, mm of plastic on inside what about this

al skin checked

put 1 mm skin-> Beni

yves sent in drift time to distance resolution, mcsmear cell dependent smearing function
