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.
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. |
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. |
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'); |
