Description	The TM-71 was designed as a manual tool with which to measure the relative three dimensional movements that occur across a discontinuity separating two adjacent blocks. It remains one of the most precise instruments of its type and more than one hundred are now permanently installed across the globe in order to record slow moving fault displacements or slope deformations. The instruments are commonly installed in caves to minimise the effects of diurnal and seasonal climatic oscillations. The data are normally recorded at each site once a month using photographic paper or a digital camera and these images are then interpreted later by the individual investigator. There have, however, been a number of recent advances that have enabled the development of a subsurface automated data logging procedure. It is now possible for an instrument installed within a cave to be equipped with loggers so that it can record data for protracted periods at a predefined interval which may be as frequent as once every ten minutes. This generates substantial amounts of data that are often difficult to interpret due to the conditions within the cave. The code presented here is able to automatically extract the four parameters needed in order to precisely measure relative three dimensional movements and has been specifically designed to overcome these interpretational problems.
