    "abstract": "In this paper we show how a two dimensional fluid model can be used to\ninterpret data obtained from an inclined Mach-probe or a Gundestrup probe. We\nuse an analytical approximation of the solution of the differential equations\ndescribing the relation between the plasma flow and the measured ion saturation\ncurrents at the probe\u0027s surface. The parameters of this analytical solution are\ndetermined by comparison with the exact numerical solution of the equations. In\nthis way we are able to measure the parallel as well as the perpendicular Mach\nnumbers over the whole parameter range with a minimum accuracy of 90%.",
