HELIOS 1&2 RANK AMONG THE MOST IMPORTANT MISSIONS IN HELIOPHYSICS AND THE MORE THAN 11 YEARS OF DATA RETURNED BY ITS SPACECRAFT REMAIN OF PARAMOUNT INTEREST TO RESEARCHERS. THEIR UNIQUE TRAJECTORIES WHICH BROUGHT THEM CLOSER TO THE SUN THAN ANY SPACECCRAFT BEFORE OR SINCE ENABLED THEIR DIVERSE SUITE OF IN-SITU INSTRUMENTS TO RETURN MEASUREMENTS OF UNPRECEDENTED SCIENTIFIC RICHNESS. THE HELIOS DATA CONTINUE TO DATE TO BE OF PRIME INTEREST TO THE SPACE PHYSICS COMMUNITY. THIS DATASET PLAYED A KEY ROLE IN THE PLANNING OF THE UPCOMING SOLAR ORBITER (SOLO) AND SOLAR PROBE PLUS (SPP) MISSIONS AND CONTINUE TO DO SO. UNDER A PAST TWO-YEAR NASA HDEE GRANT WE HAVE BEEN WORKING ON AGGREGATING ANALYZING EVALUATING DOCUMENTING ALL THE AVAILABLE HELIOS 1&2 IN-SITU DATA WITH THE GOAL OF CREATING A SINGLE COMPREHENSIVE ARCHIVE OF THE DATASET TO BE MADE PUBLICLY AVAILABLE TO THE ENTIRE COMMUNITY FOR USE IN PREPARATION OF SOLO AND SPP AND BEYOND. IT HAS BEEN A VERY TEDIOUS WORK BUT THE ARCHIVE IS ONLINE (HTTP:// HELIOS-DATA.SSL.BERKELEY.EDU) ALTHOUGH BEING A WORK IN PROGRESS AND WILL BE PUBLICLY OPEN BY MID JUNE 2017. A CAREFUL DETAILED ANALYSIS OF THE HELIOS FLUXGATE AND SEARCH COIL MAGNETIC FIELD DATA HAS REVEALED NUMEROUS ISSUES AND PROBLEMS WITH THE AVAILABLE PROCESSED DATASETS THAT WE ARE STILL WORKING TO SOLVE. THIS TASK IS NOT TRIVIAL AS THE ORIGINAL RAW DATA ARE GONE FOREVER. SIMILARLY A CAREFUL ANALYSIS OF THE PLASMA DATA HAS ALSO REVEALED ISSUES WITH THE ACCURACY OF THE AVAILABLE PLASMA MOMENTS (ION/ELECTRON DENSITY VELOCITY AND TEMPERATURE ETC) AS WELL AS OTHER ISSUES WITH THE PROCESSING OF THE VARIOUS MORE DEVELOPED PRODUCTS SUCH AS 1D (REDUCED) PARTICLE DISTRIBUTIONS AND 3D DISTRIBUTION FUNCTIONS FROM THE RAW DATA. THE PLASMA DATA IN PARTICULAR THE ION AND ELECTRON MOMENTS HAVE BEEN WIDELY USED IN THE PAST AND CONTINUE TO BE USED TO DATE WITHOUT KNOWLEDGE OR UNDERSTANDING OF THEIR ISSUES AND LIMITATIONS. HAVING RELIABLE AND ACCURATE PLASMA MEASUREMENTS WILL BE OF TREMENDOUS HELP TO THE SPP AND SO COMMUNITY WHO STRONGLY RELY ON FOREKNOWLEDGE OF THE VARIETY OF SOLAR WIND CONDITIONS THAT THEIR MISSION WILL ENCOUNTER. WE STARTED LOOKING VERY CLOSELY AT THE VARIOUS ION AND ELECTRON DATASETS AND OLD DOCUMENTS IN GERMAN THAT WE GATHERED. WE TRANSLATED THE PLASMA INSTRUMENT BLUE BOOK AND OTHER RELATED DOCUMENTATION FROM THE 80S WITH PERTINENT INFORMATION CONCERNING THE PROCESSING OF THE PLASMA DATA. THIS HELPED US TREMENDOUSLY TO SORT THROUGH THE MORE DETAILED DATASETS I.E. 1D AND 3D ION DISTRIBUTION FUNCTIONS FROM THE I1A INSTRUMENT 1D ION CURRENT MEASUREMENTS FROM THE I1B INSTRUMENT 3D ION DISTRIBUTION FUNCTIONS FROM THE I3 INSTRUMENT AS WELL AS 2D ELECTRON DISTRIBUTION FUNCTIONS FROM THE I2 INSTRUMENT. WE CAME UP WITH A VERY DETAILED PLAN TO REPROCESS THE ION AND ELECTRON DISTRIBUTION FUNCTION DATA USING MODERN FIT TECHNIQUES INSTEAD OF THE PREVIOUSLY USED MOMENT CALCULATIONS. BY FITTING A MODEL DISTRIBUTION FUNCTION TO THE MEASURED DISTRIBUTIONS WE WILL BE ABLE TO ACCURATELY CHARACTERIZE THE DIFFERENT COMPONENTS OF THE ION AND ELECTRON DISTRIBUTION FUNCTIONS. WE WILL DERIVE NEW AND MORE ACCURATE PARAMETERS OF SOLAR WIND CORE AND BEAM PROTONS CORE AND BEAM ALPHAS AS WELL AS ELECTRON CORE HALO AND STRAHL PARAMETERS. THESE PARAMETERS WILL INCLUDE DENSITY VELOCITY TEMPERATURE TEMPERATURE ANISOTROPY AND HEAT FLUX. THESE NEW PARAMETERS WILL BE ADDED TO OUR SINGLE HELIOS DATA ARCHIVE HOSTING ALL THE IN-SITU HELIOS DATA ALONG WITH VALUABLE DOCUMENTATION AND SOFTWARE. PRIOR STUDIES OF ION DATA FROM HELIOS ULYSSES WIND AND OTHER MISSION HAVE DEMONSTRATED THE COMPLEXITY OF SOLAR WIND KINETICS. BESIDES BEING OF PRIME INTEREST TO SPP AND SOLO TEAMS THE NEW HIGH-ACCURACY DATASET OF HELIOS ION PARAMETERS WILL ENABLE THE COMMUNITY TO MAKE EXCITING NEW INVESTIGATIONS INTO THE PROCESSES THAT AFFECT THE EVOLUTION OF SOLAR WIND PLASMA AS IT EXPANDS THROUGH THE INNER HELIOSPHERE.
