; Notes:
; - Data reported within this file do not exceed the limits of
; various paremeters listed in the following section. There
; may be more valid data in the original dataset that requires
; additional work to interpret but was discarded due to the
; limits.
; - We provide the one sigma uncertainty for each parameter
; produced by the non-linear curve fitting analysis either
; directly from the fitting or by propagating uncertainties
; for bulk speeds, flow angles or any other derived parameter.
; - For the non-linear anisotropic proton analysis, a scalar
; thermal speed is produced by determining parallel and
; perpendicular tmperatures, taking the trace,
; Tscalar = (2Tperp + Tpara)/3 and converting the result
; back to a thermal speed. The uncertainties are also
; propagated through

; Fit Flag Guide:
; The fit flag indicates non-ideal conditions that may affect the quality of
; the nonlinear fit and, where applicable, simplifying assumptions that have been
; taken.
;
; 10: Solar wind parameters OK -- no action necessary
; 9: Alpha particles are relatively too cold
; 8: Alpha particles overlap within protons in current distribution function.
; 7: Alphas too fast, out of SWE range
; 6: Alpha particle peak may be confused with second proton peak.
; 5: Parameters OK, but Tp=Ta constraint used (params obtained with SUB_PROT=1)
; 4: Alphas are unusually cold, Tp=Ta constraint used (SUB_PROT=1)
; 3: Alphas are relatively too hot (SUB_PROT=1). Tp=Ta constraint used
; 2: Alphas are unusually slow.
; 1: Poor peak identification
; 0: Spectrum cannot be fit with a bimax model. May be strongly non-Maxwellian or
; may contain a discontinuity.
