.. index:: ! snaphu_interp.csh ***************** snaphu_interp.csh ***************** Synopsis -------- **snaphu_interp.csh** *correlation_threshold maximum_discontinuity [///]* 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 References ---------- Chen C.
