MM1 borehole, 200–272 m, S-wave velocity anisotropy results from Rotation-scan. Track 1: max/min C1/C2 diameters from 4 arm Caliper, in red, and Gamma Ray/GR. Track 2: slownesses 40–240 μs/m: DTCO, DTSmin (red) and DTSmax (Black) from Rotation-Scan, DTS from monopole transmitter (blue), DTST/Stoneley (black, smooth curve), superimposed with the velocity anisotropy ΔV/V curve (black, high frequency). Tracks 3–5: Lithological columns.
