Estimates of the line-of-sight deformation velocity (_fitted_velocity.tif) and the estimated standard error (_fitted_se.tif) were obtained by Short-BAseline Subset (SBAS) processing. Two SBAS interferogram subsets were considered, one encompassing all years (2015-2019, filenames 1519) and one encompassing years 2015-2017 (filenames 1517). The first band of these images contains the line-of-sight velocity in (m/s), the second band the estimated displacement in the middle of the study period, referenced to the beginning of the respective study period.

Regions with questionable results (e.g., where closure analyses did not successfully correct unwrapping errors) were delineated manually in two geopackage files.
