Table 1. Interferogram and SAR data used. Master and slave indicate the period of SAR data for performing SAR interferometry. Displacement from master to slave is estimated via InSAR analysis. Off-nadir and Bperp show representative values of the off-nadir angle and perpendicular component of baseline, respectively.
