The modal frequencies of the ETMY monolithic section were measured yesterday. frequency (Hz) uncertainty Longitudinal 0.651 0.002 Pitch 1.101 0.002 Yaw 1.092 0.002 Vertical 6.72 0.03 Roll (?) 9.66 0.1 Fibre HR right 508.6 fibre HR left 513.7 fibre AR right 508.4 fibre AR left 512.5 The pitch and yaw modes are very close together. The feature at 9.7 Hz was guessed to be the roll mode. The violin mode measurement did not give a response as clear as normal but there are sharp features at the expected frequency and they make some sense in that the differential tension would indicate about 1/2 a mrad of excess pitch and we see 1 mrad
