Parallel and Perpendicular Temperatures
The parallel and perpendicular temperatures are computed as follows: 1) the eigenvalues of the DBCS temperature tensor T are computed, 2) T is projected onto the DBCS magnetic field unit vector (obtained from the magnetometer data) to compute the parallel temperature Tpar, 3) the perpendicular temperature is computed as Tperp = (Tr(T) – Tpar)/2
