Diagram showing the FMS calipers (C1 and C2) in track 1; travel-time for compressional- (DTC) and shear-waves (DTS) generated with the DSI monopole source and shear-wave travel times produced with the DSI dipole source in track 2; transmitter and receiver coherence for the high frequency compressional-wave monopole source (CHTP and CHRP) in track 3; and transmitter and receiver coherence produced by the high frequency shear-wave monopole source (CHTS and CHRS) as well as coherence from the low frequency shear-wave dipole source (CHR2) in track 4.
