This is the main folder for the NEIC PDE archives (basically the NEIC catalog out of Hydra rather than a merged view out of ComCat). These files are in ISF format. Data are organized such that there is one folder per year. Within each year folder, the file names for the NEIC catalogs use the convention YYYYWW_cat.isf where: YYYY is the year WW is the number of the week within the year
