RELATION RECORD SPECIFICATION
This record type is used to define the relation between the field record number and shotpoint and between recording channels and receiver groups. For each shotpoint there is at least one "Relation Record". Each of these records specifies a section of consecutively numbered channels and receiver groups. After a numbering gap or a change in line name or repositioning for the receiver groups a new "Relation Record" has to be given. Channel numbers should be in ascending order.
Fields 6,7 and 8 must be identical to fields 2,3 and 4 of the corresponding shotpoint record. While the receiver line and point numbers in fields 13,14 and 15 must be the same as used in the receiver point records.
