Which kind of Offset-Tracking is applicable to do decomposition

Dear all,

Recently, I tried to do the offset-tracking using the ISCE for two case studies and found some enjoyable signals, overlapped with the interferograms. You can see them in the following:

As you know, this information is very useful to see whether the horizontal displacement happened or not and also find the location of trace caused by the fault plane. Now, I was wondering about which kind of offset tracking results can be used to do the 3D decomposition? Results from the radar offset tracking or sub-pixel correlation using the high-resolution optical images?
