PSCAN Structure

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).
