Top Wind/SWE readme (for https://spdf.gsfc.nasa.gov/pub/data/wind/swe/ascii/) This directory contains Wind/SWE definitive proton and alpha particle plasma parameters determined by non-linear anisotropic fitting of bimaxwellian distribution functions to measured plasma distributions, as well as "key parameter" (KP) data produced and made community-accessible very quickly, originally as part of the ISTP program. Production of the definitive data was interrupted in late 2004, pending availability of more precisely determined ambient magnetic field vectors. A newly reprocessed version of the definitive SWE data became available in 2012, extending back to the mission start in 1994. This new data product is accessible from the "2-min" subdirectory of this directory. The "2-min" subdirectory itself has a subdirectory through which the superseded 1994-2004 definitive data remain accessible. (The SWE measurement cycle is ~92s; "2-min" is an historical approximation to 92s.) The KP data are accessible through the subdirectory "swe_kp_unspike" along with a readme file describing the progressive stages of KP data cleaning. The file 1m_mrgd_mag_plasma.txt links to Wind 1-min field-plasma(SWE)-merged, bowshock-nose-shifted data used in creating 1-min OMNI data and 1-min merged data as well. The ion portion of SWE (Solar Wind Experiment) is a Faraday Cup instrument. SWE Principal Investigator is Keith Ogilvie of NASA/GSFC. The main Coinvestigator for the Faraday Cup is Alan Lazarus of MIT. Key contributor from many years has been Justin Kasper, originally a Ph.D. candidate at MIT and now at Harvard's Center for Astrophysics. The lead SWE/ion scientist in very recent years is CfA's Michael Stevens who implemented the 2012 SWE data reprocessing. -----------------------------------------------------
