Supporting data and code for: Millstone Hill ISR Measurements of Small Aspect Angle Spectra

Main code is contained in Matlab .m files. Path dependencies may need to be fixed but there are no duplicate file names.

acf_data_plot.m  is used to plot the ACFs measured by Millstone

acf_fitting.m  is used to fit the Millstone ACFs to the Brownian theory. Calls isr_theory_fn.m to calculate Brownian ACF

acf_fitting_plots.m  plots the fitted and measured ACFs

acf_fitting_plots_spcomp.m  plots the ACFs from the single-particle simulations

acf_fitting_plots_piccomp.m  plots the ACFs from the PIC code

sp_fit_to_brownian.m  fits the single-particle simulations to Brownian theory

The single particle simulations are produced by singleparticle5.m. The full ACFs are then calculated by running merge.m to combine the simulation results, gordeyev.m to calculate the electron Gordeyev integral, Ji_calc.m to calculate the ion Gordeyev integral, and finally isr_Jtoneb.m to calculate the spectra. The resulting spectra are included and labeled as 'neb_sp12_Te_Ti.mat' for the different electron and ion temperatures. The Brownian spectra for the same parameters are labeled as 'neb440_Te_Ti.mat'. The frequencies used in calculating the electron Gordeyev integrals may be needed for plotting and are labeled as 'wJe_12_Te_Ti.mat'.

The data are labeled by the date, Nov_2013, Feb_2019, or Apr_2019. An appendix of 'avg' indicates the file averaged the ACFs across multiple range gates. The measured ACFs are all labeled 'acf_pos?_date_avg_fitted.h5', where pos? refers to the antenna pointing direction. The pointing directions and associated parameters are located in 'looker?_date_avg.csv'. The IRI model results for each experiment are in the files 'iri?_date_avg.m'.

The spectra from PIC simulations are included as 'k*_T1150_N5e10_nz.mat', where * is an aspect angle index. The matching k* and aspect angles in degrees are {k4, 0.8}, {k6, 1.2}, {k11, 2}, {k15, 2.8}, {k20, 3.6}, {k24, 4.4}, {k28, 5}, {k29, 5.2}, {k34, 6}, {ky, 0}, {kx, 90}. The files 'neb_spPIC_fb_Te1145_Ti1145.mat' and 'neb440_Te1145_Ti1145.mat' are respectively the single-particle and Brownian spectra calculated with the same parameters as the PIC code.
