        "Description": "Wind Suprathermal Ion Composition Spectrometer (STICS) phase-space distribution functions at 1-day time resolution for specified ions. 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.",

However, to avoid confusion and misunderstanding, it is recommended that users consult STICS Instrument Team before publishing work derived from the data. The STICS Instrument Team has worked hard to minimize 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 team members are not consulted before publication. At the very least, preprints should be forwarded to the STICS Instrument Team before publication.",
