Calibrated science quality data presented in the native spacecraft frame. The data files contain 3D phase space density distribution, A(v) (currently in arbitrary units) functions, for H+. There are 512 values for A(v) for each time step, corresponding to each directional sector (16 total directions) and each Deflection Voltage Step (DVS) corresponding to a set E/q value (32 total voltage steps per sector). Only proton distribution functions are currently released at the production level.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://vho.nasa.gov/mission/wind/sms/3d/wind_stics_lv2_release_notes_01Apr2010.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://space.umd.edu/wind/sms.html#STICS", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "https://doi.org/10.48322/naj7-dg41", "keyword": ["ioncomposition"], "landingPage": "https://doi.org/10.48322/naj7-dg41", "license": "https://www.usa.gov/government-works", "modified": "2026-04-06", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "VHO and VMO Data Repository at NASA/GSFC"}, "theme": ["Heliophysics"], "title": "Wind Suprathermal Ion Composition Spectrometer (STICS) Distribution Functions"}
