        "text": "A temporary grid system will be established over the site and marked out using canes. The location of the grid will be set out using an RTK GPS system theoretically accurate to some 0.01m and referenced to OS co-ordinates. Hand Held: Data will be collected using a Bartington Grad 601-2. The instrument consists of two paired sensors (see below) and readings are logged at 0.25m centres along traverses 1.0m apart across 30m grids. The collection of data at 0.25m centres provides an appropriate methodology balancing cost and time with resolution as per Historic England guidelines. Two sensors mounted 1m horizontally apart and very accurately aligned to nullify the effects of the earth's magnetic field. Readings relate to the difference in localised magnetic anomalies compared with the general magnetic background. The magnetometry survey has not recorded any magnetic responses that could be interpreted as being of definite archaeological interest. A number of linear trends and a zone of increased magnetic response have been detected and assigned to the category of uncertain. These anomalies are likely to be a product of modern agricultural or natural processes. Two former field boundaries are visible in the magnetic data along with ridge and furrow ploughing. The locations of land drains have also been mapped.",
