snaphu_interp.csh

Synopsis

snaphu_interp.csh correlation_threshold maximum_discontinuity [<rng0>/<rngf>/<azi0>/<azif>]

Description

snaphu_interp.csh Unwrap the phase while interpolating around NaN pixels

Required Arguments

correlation_threshold

Correlation is set to zero is less than the set threshold (if unsure what threshold to start with, try creating a coherence mask first to check)

maximum_discontinuity

Enables phase jumps for earthquake ruptures, etc. Set to 0 for continuous phase such as interseismic or up to 60 for an event such as an earthquake rupture

Optional Arguments

optional range

If you wish to only process a subarea of your input, specify minrange/maxrange/minazimuth/maxazimuth

Example

snaphu_interp.csh .12 40 1000/3000/24000/27000
