Vector size computation is incorrect

[demiangomez]

Size of coseismic displacement does not correspond to the actual size. For example, see TERO

See time series magnitude (2015 event): arg.tero : 0.000 -0.000 0.000

vector should be almost invisible based on the size of CATA

CATA time series: arg.cata : -0.003 -0.010 0.001
