      Hi,

      I have some doubts about the stratification procedure for the APS estimation. More specifically, what is the meaning of MaxR and DSF. How SARPROZ estimates the vertical variation of the APS delay?

      Thank you

      DSF is DownSamplingFactor
      Because APS is low frequency signal then the APS results will be multilooked in that factor

      The stratification in Sarproz is estimated as the APS component correlated with the topography.
      If you flag that option, Sarproz will estimate a coefficient and build a model based on the external DEM and on the estimated coefficient. That model will become part of the APS estimated and removed from interferograms.
      We advise you to use it only in situations where the simple default model fails.
      best
