Upstream Density, Velocity, and Temperature
CAPS Solar wind data, doy 279-353, 2001
Calculated by fits to CAPS/IBS data assuming a Maxwellian distribution
f(v)=n/(a^3 pi^1.5) exp(-(v-w)^2/a^2 )
The thermal velocity, a, is not considered reliable when a < 0.02 w.
(We can probably do better than that, but not with currently-available
PRELIMINARY, uses best fitting routines as of 26 FEB 02.
May be revised as new data analysis software becomes available.
