Hi Cecilia,

yes, on the manual you find some explanation, here in particular http://sarproz.com/manual/geocod.html

what you have written is correct if no correlation with temperature was estimated. If on the contrary you did remove a temperature-correlated trend, then you have to tick on the corresponding box to see it, otherwise it is removed from the displayed data.

Yes, it is correct, if you want to look at the correlation of residues with other factors, then better to look at the residues alone.

And yes, this can work also for non-linear components.

Tricks in Sarproz:

– to estimate non-linear movement (assuming it has a temporal correlation), input smart=5 in the corresponding time series processing module. This corresponds to a 5 samples time filter. it’s non-parametric movement estimation.

– To estimate correlation with external factors as water level, you can import them as “aux data” and then estimate a correlation value in the “azimuth pos” box in time series processing parameters. Here a few notes http://sarproz.com/manual/scegli_dataset.html
