INAF-IAPS Solar Orbiter-PAS data
================================

.. contents:: Table of contents

The product contains density N, speed vector V, pressure  tensor P, temperature components (Tx, Ty, Tz), and the velocity of the satellite V_solo,  computed using the data collected by the Proton-Alpha Sensor (PAS) onboard Solar Orbiter. 
PAS  measures the 3D distribution functions of the dominant ions of the solar wind, from 200 eV to 20 KeV, without mass and charge selection. In practice, this concerns mostly the proton and alfa populations (unseparated). At full resolution, PAS collects the 3D ion distribution function in about 1 second, even though the moments have a cadence of 4 seconds, while in “snapshot” mode the phase space sampling is reduced, allowing a greater cadence for the moments.
