- note:
-- several landslides
-- co- and post-seismic fault motion
-- fast subsidence

The data consists of the following files:

*.spo_range.geo.tif - raw range offsets measured in meters

*.spo_snr.geo.tif - signal-to-noise ratio that can be used to remove noisy pixels

*.spo_range.geo_SNR5_FILTER_MEDIAN3km.tif - post-processed range offsets measured in meters
- The following post-processing filters provided in readme.txt files are applied:
- pixels with SNR<5 (or 10) are removed
- pixels with abs(range)>5 are removed
- median filter with a 3km window is applied
- different filtering parameters can be applied, if needed.

Files produced with GAMMA look_vector command (measured in radians):
*.lv_theta.geo.tif - SAR look vector elevation angle at each map pixel
- lv_theta: PI/2 -> up -PI/2 -> down
- The elevation angle is measured between the surface and the look vector pointing at the radar
*.lv_phi.geo.tif - SAR look vector orientation angle at each map pixel
- lv_phi: 0 -> East PI/2 -> North

*qc - various information about processing options and baselines.

For extracting 2D time series for individual pixels use msbas_extract command and MSBAS_TSOUT.txt file with timing information.
