FILTSUBTRACT subtracts a frequency dependent noise contribution from an input ao. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: FILTSUBTRACT subtracts a frequency dependent noise contribution from an input ao. The method computes the transfer function between both input AOs and fits a miir model to it. The frequency band is applied is set by a threshold in the coherence that the user defines as an input parameter. CALL: c = filtSubtract(a,b pl) INPUTS: a - AO from where subtract linear contributions b - AOs with noise contributions pl - parameter list (see below) OUTPUTs: c - output AO with contributions subtracted (tsdata) Parameters Description VERSION: $Id: filtSubtract.m,v 1.21 2012/03/06 16:37:35 miquel Exp $ TODO: handling errors split by coherence function %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
