Block VI: Receivers

The default specification of the virtual source/receiver arrays used for coupling the field between the sectors is the same as for RDOAST, i.e. through the parameters RD1, RD2 and NRD in Block VI, with

RD1

Depth of uppermost virtual source/receiver in meters

RD2

Depth of lowermost virtual source/receiver in meters

NRD

Number of virtual source/receivers

The NRD receivers are placed equidistantly in the vertical.

The physical receiver depths are specified similarly on a separate line. It should be noted that for each depth, the code will compute the field at the closest virtual receiver depth.

D1

Depth of uppermost physical receiver in meters

D2

Depth of lowermost physical receiver in meters

ND

Number of physical receiver depths
