KEYWORDS: DATA: Raw data can be returned through this named variable. NVDATA: Raw non-varying data can be returned through this variable. POLAR: Computes polar coordinates if set. TIME_RANGE: 2 element vector specifying the time range. VTHERMAL: if nonzero, calculates ion thermal velocities. RESOLUTION: Returns data at a given time resolution. In seconds.
