Vlasiator 3D run (EGI) soft X-ray emission maps

This dataset contains soft X-ray emission maps generated from the outputs of a 3D run of the Vlasiator near-Earth space model (Palmroth et al., 2018, https://doi.org/10.1007/s41115-018-0003-2) with southward interplanetary magnetic field driving. These data correspond to the results presented in Grandin et al. (2024, https://doi.org/10.26464/epp2023052), where details on the simulation setup and soft X-ray emission calculation can be found. The frame of reference for the data is Geocentric Solar Ecliptic (GSE).
The dataset includes three types of data saved as NumPy array binary files:
(i) 1D NumPy arrays giving the ranges of azimuth and elevation angles associated with the soft X-ray image pixels;
(ii) 2D NumPy arrays containing the line-of-sight-integrated soft X-ray images in the GSE XY plane, that is, obtained considering a virtual imager placed above the North Pole of the Earth at (0, 0, 30 Re), with Re = 6371 km the Earth radius, and looking towards the equatorial plane;
(iii) 2D NumPy arrays containing the line-of-sight-integrated soft X-ray images in the GSE XZ plane, that is, obtained considering a virtual imager placed on the dawn side of the Earth at (0, –30 Re, 0) and looking towards the noon–midnight meridional plane.
The soft X-ray maps are given at a 1 s time resolution for simulation time stamps from 800 s to 1506 s. The corresponding images have an angular resolution of 1/3° in azimuth and elevation.
