  1. Letters in column EQ represent interferograms that include F: before the main shock (April 16, 2016, M w 7.0), foreshocks only; M: the date of the main shock; and A: after the main shock only. Des and Asc stand for descending and ascending orbits, respectively. Letters H, U, V and W indicate Stripmap (6 m resolution), Stripmap (3 m resolution), ScanSAR (490 km swath) and ScanSAR (350 km swath) modes, respectively
  2. B p perpendicular baseline
