If the image above appears blurry, or you would like to see a larger image, please view the full-sized image of the RLR diagram.
Because of subsidence at the station site the RLR factor was adjusted annually throughout the dataset.
It is therefore not possible to quote a specific RLR factor. See the attached documentation
for futher information.
RLR (1995) is 11.5m below BM No. 12
