assoccoo Columns

ColumnName | Domain | Datatype | NULL | Definition
orid |  | NUMBER(15, 0) | NO | Origin identification. Each origin is assigned a unique positive integer which identifies it in the database. The orid is used to identify one of the many hypotheses of the actual location of the event
coid |  | NUMBER(15, 0) | NO | Coda identification. Each coda is assigned a unique positive integer which identifies it in the database
commid |  | NUMBER(15, 0) | YES | Comment identification. This is a key used to point to free-form comments entered in the Remark relation. These comments store additional information about a tuple in another relation. Within the Remark relation, there may be many tuples with the same commid and different lineno, but the same commid will appear in only one other tuple among the rest of the relations in the database
auth |  | VARCHAR2(15) | NO | The auth field specifies the source of the information. This may be a network identifier (FDSN or otherwise), or any other string indicating the source of the information in the record
subsource |  | VARCHAR2(8) | YES | A second identifier to specify a unique source within the domain specified by auth

The location of the origin is specified in the origin record referenced by the attribute orid. The attribute arid points to the record in the Arrival relation that identifies the receiver. The value of the attribute can exceed 180 degrees, it can even exceed 360 degrees, the geographic distance between source and receiver is delta mod(180)
seaz |  | NUMBER(7, 4) | YES | Station to event azimuth. This attribute is calculated from the station and event locations. It is measured clockwise from North
