SWICS measures the distribution functionsof the interstellar cloud and dust cloud pickup ions up to energies of 100 keV/e.For more information about the SWICS instrument, visit the SWICS Home Page at http://solar-heliospheric.engin.umich.edu/ace.The quality of ACE level 2 data is such that it is suitable for serious scientific study. However, to avoid confusion and misunderstanding, it is recommended that users consult with the appropriate ACE team membersbefore publishing work derived from the data. The ACE team has worked hard to ensure that the level 2 data are free from errors, but the team cannot accept responsibility for erroneous data, or for misunderstandings about how the data may be used. This is especially true if the appropriate ACE team members are not consulted before publication. At the very least, preprints should be forwarded to the ACE team before publication. <_Description>Source: Master/CDFglobalAttributes/TEXT <_Acknowledgement>Source: Master/CDFglobalAttributes/Acknowledgement <_Rights> SPDX Creative Commons Zero v1.0 Universal https://spdx.org/licenses/CC0-1.0.html https://spdx.org/licenses/ Please acknowledge the Principal Investigator, G.
