ABSTRACT

The dataset consists of a cube of raw velocity data from the Michelson Doppler Imager (MDI) instrument aboard the SOHO satellite. The data have been transformed to Cartesian coordinates by projecting high-resolution data from an area approximately 18$^\circ$ square onto a tangent plane. The object in the center of the time-slice (top of cube) is a sun-spot. The sampling spacing is 1 minute on the time-axis and approximately 825 km on the two spatial axes.
