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