Performance tests of a set of Gough-Reitzel magnetic variometers
Abstract
Results of field tests of twenty-one magnetic variometers of the Gough-Reitzel (1967) pattern are reported. The lenses of these instruments were achromatic, and all timing was controlled electronically. It was found that while single scalings of a record can be made with a standard deviation of order .2 nT, the record itself is likely to be in error with a standard deviation of 1.5 nT. The causes of this error are inconsistency and nonlinearity in the sensor responses during both recording and calibration.
