The PSCAN structure is a structure to contain the output of MKSCANP. This routine scans epicentral distance as function of ray parameter and take off angle for a given phase and source depth. Empty PSCAN structures are returned by MKEMPTYPSCAN.
Field | Type | Units | Description |
---|---|---|---|
.phase: | string | - | Name of the phase for which this struct is valid |
.h: | scalar | km | focal depth for which this struct is valid |
.angles: | array | deg | list of take off angles |
.p: | array | sec/deg | list of ray parameters correpsonding to the take off angles at depth h |
.dist: | array | deg | list of epicentral distances corresponding to p. |
.vp: | scalar or 2-element array | km/s | P wave velocity at focal depth |
.vs: | scalar or 2-element array | km/s | S wave velocity at focal depth |
.starts: | array | index | positions where continuous pieces of dist(p) begin |
.ends: | array | index | positions where continuous pieces of dist(p) end The i-th continuous piece begins at starts(i) and ends at ends(i). |
