Derivative products from "Spherical Harmonic Representation of Energetic Neutral Atom Flux Components Observed by IBEX" by Swaczyna, Dayeh, & Zirnstein

This dataset includes derivative data products obtained using the method described in: Swaczyna, Dayeh, & Zirnstein (2023), Spherical Harmonic Representation of Energetic Neutral Atom Flux Components Observed by IBEX

The products have been derived from IBEX Data Release #16 (https://ibex.princeton.edu/DataRelease16). 

hvset_tabular_ram_cg.zip - results for ram-only Compton-Getting and survival probability corrected IBEX maps

hvset_tabular_antiram_cg.zip - results for antiram-only Compton-Getting and survival probability corrected IBEX maps

Each archive includes the following files:

com_flux_yyyy_esa_e.txt - reconstructed flux map from spherical harmonic coefficients using the standard IBEX pixelization

com_fvar_yyyy_esa_e.txt - reconstructed flux variance map from spherical harmonic coefficients using the standard IBEX pixelization

com_ylm_coeff_yyyy_esa_e.txt - coefficients of the spherical harmonic representation

com_ylm_mat_yyyy_esa_e.txt - covariance matrix providing uncertainties of the coefficients

mask_ribbon_esa_e.txt - ribbon mask

matrix_y.txt - matrix transforming the spherical harmonic coefficients into values in IBEX pixels

where:

com - indicate the included component of the ENA flux:

gdf - Globally DIstirbuted Flux

rib - IBEX ribbon

tot - both components (total maps)

e - enumerates IBEX energy steps (e = 2, 3, ... 6)

yyyy - indicates map year (yyyy = 2009, 2010, ..., 2019 or 'single' for the time-combined map)
