Method ao/filtSubtract


  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)
