LOC structure

The LOC structure contains only those nodes that are most compatible with the data set. This is intended to be mainly a 4D "list" of points that are acceptable as hypocenters. Details of the structure are different for the different grid types.

Common to all grid types
Field Type Units Description
.type string - grid type string, as in lsopt.grid_type.
.maxfit number The degree of compatibility of the returned nodes, i.e. the number of data to which they are compatible.
Triangular grids only
Field Type Units Description
.nodelist numeric array [deg deg km] List of 3D coordinates of nodes.
nodelist(i,1): i-th node longitude [deg]
nodelist(i,2): i-th node latitude [deg]
nodelist(i,3): i-th node radius [km]
.origintime structure - Sub-structure containing origin time interval information.
ORIGINTIME sub-structure (Triangular grids only)
Field Type Units Description
.id number - ID of the corresponding node in the original grid structure.
starts numeric array [sec] start times of possible origin time intervals
ends numeric array [sec] end times of possible origin time intervals. The i-th origint time interval begins at .starts(i) seconds and ends at ends(i) seconds. Time is counted since mklsconstants('ReferenceDay');
