Datasets ============= MHD-based model data files (*.npy) can be found in ``/modeling/cn`` and ``/modeling/cs`` and it should be downloaded separately, on the directory that the code will be run. Optional: virtual sc trace file * Note that this file does not need to be manually generated if spacecraft orbit is available on SSCWeb. * text format: (without header) * yy/mm/dd HH:MM:SS x y z, as in SSCWeb (x,y,z in GSE Earth radii)
