        "Description": "The SWICS 12-minute proton data contains densities, speeds, and thermal speeds\nfrom the beginning of the mission up to the present day. The densities have\nbeen cross-calibrated to the proton monitors ACE/SWEPAM and WIND/SWE, and\nrepresent a continuous data set that can be used in conjunction with other\nSWICS data, or as a stand-alone measurement. For details on the SWICS proton\ndata, see the release notes provided by the instrument team:\nhttp://www.srl.caltech.edu/ACE/ASC/DATA/level2/ssprotons/swics_protons_release_notes.txt",
