delta

Base Entity | assocaro
Attribute Name | delta
Logical Rolename |
ColumnName | delta
RoleName |
Definition | Source-receiver distance. This attribute is the arc length, over the earth’s surface, of the path the seismic phase follows from source to receiver. 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.
Note |
    Range:		delta >= 0.0

    Units:		Kilometers

seaz

Base Entity | assocaro
Attribute Name | seaz
Logical Rolename |
ColumnName | seaz
RoleName |

in_wgt

Base Entity | assocaro
Attribute Name | in_wgt
Logical Rolename |
ColumnName | in_wgt
RoleName |
Definition | Input weight. Hypoinverse station archive card columns 17 & 50: 0, 1, 2, 3 --> 1.00 4, 5, 6, 7, 8, 9 --> 0.00
Note |
    Range:		0.0 < in_wgt <= 1.0
    		0.0 = no weight (not used)

wgt

Base Entity | assocaro
Attribute Name | wgt
Logical Rolename |
ColumnName | wgt
RoleName |
Definition | Location weight. This attribute gives the final weight assigned to the allied arrival by the location program. It is used primarily for location programs that adaptively weight data by their residuals. Raw values from hypoinverse columns 39 & 64
Note |

timeres

Base Entity | assocaro
Attribute Name | timeres
Logical Rolename |
ColumnName | timeres
RoleName |
Definition | Time residual. This attribute is a travel time residual, measured in seconds. The residual is found by taking the observed arrival time (saved in the Arrival relation) of a seismic phase and substracting the expected arrival time. The expected arrival time is calculated by a formula based on earth velocity model, an event location and origin time, the distance to the station, and the particular seismic phase
