I have fit all of the LSC whitening filters using vectfit4.m
All the data is in my folder ..../users/jenne/LSC_WhiteningTest_29June2011/
The zpk info is saved with each plot of the fit. The pdfs are kind of huge to stitch together (or rather my computer doesn't want to do it), so I'll just post a representative one for now.
During the daytime either tomorrow or Friday I'll adjust the actual dewhitening filters to match the measured zpk values.
