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

<p>Main code is contained in Matlab .m files. Path dependencies may need to be fixed but there are no duplicate file names.</p> <p>acf_data_plot.m&nbsp; is used to plot the ACFs measured by Millstone</p> <p>acf_fitting.m&nbsp; is used to fit the Millstone ACFs to the Brownian theory. Calls isr_theory_fn.m to calculate Brownian ACF</p> <p>acf_fitting_plots.m&nbsp; plots the fitted and measured ACFs</p> <p>acf_fitting_plots_spcomp.m&nbsp; plots the ACFs from the single-particle simulations</p> <p>acf_fitting_plots_piccomp.m&nbsp; plots the ACFs from the PIC code</p> <p>sp_fit_to_brownian.m&nbsp; fits the single-particle simulations to Brownian theory</p> <p>&nbsp;</p> <p>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 &#39;neb_sp12_Te_Ti.mat&#39; for the different electron and ion temperatures. The Brownian spectra for the same parameters are labeled as &#39;neb440_Te_Ti.mat&#39;. The frequencies used in calculating the electron Gordeyev integrals may be needed for plotting and are labeled as &#39;wJe_12_Te_Ti.mat&#39;.</p> <p>&nbsp;</p> <p>The data are labeled by the date, Nov_2013, Feb_2019, or Apr_2019. An appendix of &#39;avg&#39; indicates the file averaged the ACFs across multiple range gates. The measured ACFs are all labeled &#39;acf_pos?_date_avg_fitted.h5&#39;, where pos? refers to the antenna pointing direction. The pointing directions and associated parameters are located in &#39;looker?_date_avg.csv&#39;. The IRI model results for each experiment are in the files &#39;iri?_date_avg.m&#39;.</p> <p>&nbsp;</p> <p>The spectra from PIC simulations are included as &#39;k*_T1150_N5e10_nz.mat&#39;, 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,&nbsp;3.6}, {k24, 4.4}, {k28, 5}, {k29, 5.2}, {k34, 6}, {ky, 0}, {kx, 90}. The files&nbsp;&#39;neb_spPIC_fb_Te1145_Ti1145.mat&#39; and &#39;neb440_Te1145_Ti1145.mat&#39; are respectively the single-particle and Brownian spectra calculated with the same parameters as the PIC code.&nbsp;</p> <p>electrostatic_meteor_ablation_sim-master.zip contains an archive of the EPPIC code when it was run, see manuscript for a Github link for&nbsp;the current version of EPPIC</p>
