The SYN structure is used to store a phase synopsis for a given epicentral distance and focal depth, similar to the "Phase summary" section in the IASP91 Booklet (Kennett, 1991).
Field | Type | Units | Description |
---|---|---|---|
delta | numeric | ° | Epicentral distance for which travel times were computed |
h | numeric | km | focal depth for which travel times were computed |
name | string | - | name of the model for which travel times were computed (usually taken from the .name field of a model-structure). |
names | string matrix | - | List of Phase names for which travel times are given. |
ttimes | numeric array | s | List of arrival times of the phases listed in the names field. ttimes(i) corresponds to names(i,:). |
p | numeric array | s/° | Ray parameters at which the phases arrive. |
d | numeric array | ° | Epicentral distances at which phases arrived (in order to document roundoff errors in slowness estimation) |
a | numeric array | ° | Take off angle at which phase left the source |
