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 ; ; ; Limits: ; Minimum mach number: 1.5000000 ; Maximum chisq/dof: 100000.00 ; Maximum uncertainty in any ; parameter from non-linear ; analysis: 70.0000[%] ; ; Total number of spectra in this period: 42330 ; Spectra after applying limits: 39173 ; Spectra removed as time regressions: 0 ; Spectra removed as spikes: 505 ; Spectra written to this file: 37427 ; Spectra with alpha particle data: 29325 ; ; ; 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. ; ; ; Format Code: (i4.4," ", f11.6," ", i4.2,18(" ",f7.1),2(" ",f9.3),14(" ",f7.1),2(" ",f9.3)," ",f6.1,7(" ",f7.1)," ",f9.3,10(" ",f9.3),2(" ", f11.6)) ; ; Column # Desciption ; 1 Year ; 2 Fractional day of year (FDOY) of start of spectrum (Noon on January 1 = 1.5) ; 3 Fit flag (see table) ; 4 Proton bulk speed V (km/s) from non-linear analysis ; 5 One sigma uncertainty in V [km/s] ; 6 Proton velocity component Vx (GSE, km/s) from non-linear analysis ; 7 One sigma uncertainty in Vx [km/s] ; 8 Proton velocity component Vy (GSE, km/s) from non-linear analysis ; 9 One sigma uncertainty in Vy [km/s] ; 10 Proton velocity component Vz (GSE, km/s) from non-linear analysis ; 11 One sigma uncertainty in Vz [km/s] ; 12 Scalar proton thermal speed (km/s) trace of anisotropic temperatures ; 13 One sigma uncertainty in trace thermal speed ; 14 Proton thermal speed Wperpendicular (km/s) from non-linear analysis ; 15 One sigma uncertainty in Wperpendicular [km/s] ; 16 Proton thermal speed Wparallel (km/s) from non-linear analysis ; 17 One sigma uncertainty in Wparallel [km/s] ; 18 East-West flow angle (degrees) ; 19 One sigma uncertainty in EW flow angle ; 20 North-South flow angle (degrees) ; 21 One sigma uncertainty in NS flow angle ; 22 Proton number density Np (n/cc) from non-linear analysis ; 23 One sigma uncertainty in Np [n/cc] ; 24 Alpha bulk speed V (km/s) from non-linear analysis ; 25 One sigma uncertainty in V [km/s] ; 26 Alpha velocity component Vx (GSE, km/s) from non-linear analysis ; 27 One sigma uncertainty in Vx [km/s] ; 28 Alpha velocity component Vy (GSE, km/s) from non-linear analysis ; 29 One sigma uncertainty in Vy [km/s] ; 30 Alpha velocity component Vz (GSE, km/s) from non-linear analysis ; 31 One sigma uncertainty in Vz [km/s] ; 32 Scalar alpha thermal speed (km/s) trace of anisotropic temperatures ; 33 One sigma uncertainty in trace Alpha thermal speed ; 34 Alpha thermal speed Wperpendicular (km/s) from non-linear analysis ; 35 One sigma uncertainty in Alpha Wperpendicular [km/s] ; 36 Alpha thermal speed Wparallel (km/s) from non-linear analysis ; 37 One sigma uncertainty in Alpha Wparallel [km/s] ; 38 Alpha number density Na (n/cc) from non-linear analysis ; 39 One sigma uncertainty in Na [n/cc] ; 40 CHISQ/DOF for this fit ; 41 Proton bulk speed (km/s) from moment analysis ; 42 Proton velocity component Vx (GSE, km/s) from moment analysis ; 43 Proton velocity component Vy (GSE, km/s) from moment analysis ; 44 Proton velocity component Vz (GSE, km/s) from moment analysis ; 45 Proton thermal speed W (km/s) from isotropic moment analysis ; 46 Proton thermal speed Wperpendicular (km/s) from bimax moment analysis ; 47 Proton thermal speed Wparallel (km/s) from bimax moment analysis ; 48 Proton number density Np (n/cc) from moment analysis ; 49 Magnetic field component Bx (GSE, nT) averaged over plasma measurement ; 50 Magnetic field component By (GSE, nT) averaged over plasma measurement ; 51 Magnetic field component Bz (GSE, nT) averaged over plasma measurement ; 52 Angluar deviation of magnetic field over plasma measurement [degrees] ; 53 Deviation in magnitude of field over plasma measurement [nT] ; 54 X (GSE) Position of Wind S/C at start of spectrum [Re] ; 55 Y (GSE) Position of Wind S/C at start of spectrum [Re] ; 56 Z (GSE) Position of Wind S/C at start of spectrum [Re] ; 57 Y (GSM) Position of Wind S/C at start of spectrum [Re] ; 58 Z (GSM) Position of Wind S/C at start of spectrum [Re] ; 59 Fractional day of year (FDOY) when peak charge flux was observed (Noon on January 1 = 1.5) ; 60 One sigma uncertainty in FDOY of peak charge flux ;
