Empirical Modeling Data Set Format A complete data set consists of three record of each and is calculated from the average of 1 minute accumulation of data. The first record contains the date/time, selected OA and geophysical parameters, and data derived from the temperature derived from the fit to the z-head RPA curves, the second record contains data derived from this temperature minus the standard deviation to the fit, and the third record contains data derived from this temperature plus the standard deviation. Densities are in cm-3, temperatures in K, and potential in V. #BTYES DESCRIPTION Record 1 12 iyydoy, ihhmmss, itime(millisec of first record) (3xi4) 36 re, smlong_sc, smlat_sc, smlat_sun, calc_mlt, shell_l, bfsm(x,y,z) (9xr4) 4 Kp (1xi4) 4 f10.7(1xr4) 4 flag_gen (1xi4) *20 temp_pz(5) (5xr4) <- was ..pz(1,5) 20 flags_pz(5) (5xi4) <- was ..pz(1,5) *20 temp_mz(5) (5xr4) <- was .._pz(5) 20 flags_mz(5) (5xi4) *20 temp_z(5) (5xr4) *20 flags_z (5xi4) *20 den_tmp(5) (5xr4) *20 pot_tmp(5) (5xr4) *20 chisqr_tmp(5) (5xr4) *20 flags_tmp(5) (5xi4) * 4 avg_pot (1xr4) * 4 pot_flag (1xi4) *20 den_pot(5) (5xr4) *20 temp_pot(50 (5xr4) -> was temp_rd *20 chisqr_pot(5) (5xr4) *20 flag_pot(5) (5xi4) Record 2 248 * lo values Record 3 248 * hi values Msc variable descriptions temp_pz : plus z head temperature temp_mz : minus z head temperature temp_z : 'average radial head temperature' (calculated from avaliable Z head temperatures) den_temp : density from fit to radial head data with temperature (temp_z) held constant pot_temp : potential from fit to radial head data with temperature (temp_z) held constant avg_pot : weighted average of H+ and He+ potentials (pot_temp) -> should it be (avg_pot) den_pot : density from fit to radial head data with potential (avg_pot) held constant temp_pot : temperature from fit to radial head data with potential(avg_pot) held constant Ion order: 1: L/H+ 2: L/He++ 3: H/He+ 4: H/O+ 5: H/O++
