For information concerning use of the IS☉IS data please refer to the Energetic Particle Data User Guide available from the PSP IS☉IS Science Operations Center, SOC, web site hosted by the University of New Hampshire. The energetic particle pitch angle calculations are made possible via use of magnetic field data provided by the PSP FIELDS team. The public data reflect current instrument calibration as determined by the IS☉IS science team. Calibration efforts are ongoing and the public data will be updated over the course of the mission based on improved understanding of instrument response to the near-Sun energetic particle environment. IS☉IS visualization tools are provided as a quicklook utility for the community to better access the IS☉IS data and are also under continual development. While we make every effort to ensure their accuracy, the IS☉IS team cannot guarantee that they are error-free. For questions regarding the use of IS☉IS data, please contact Colin Joyce (cjjoyce@princeton.edu). Refer to the following web site concerning the Rules of use for the IS☉IS energetic particle data: https://spp-isois.sr.unh.edu/ISOIS_Terms_of_Use.html. The PSP IS☉IS effort is funded as part of the NASA Parker Solar Probe mission under contract NNN06AA01C.

The clock angle is nominally equal to zero meaning roughly ecliptic north. The clock angle ascends in the right-handed, counter clockwise, CCW, sense despite its name. So, positive values indicate directions toward the negative T-axis, which is opposite the ram direction, and negative values indicate directions toward positive T-axis or equivalently into ram. Undefined, that is fill, clock angle values occur if the Sun Angle is small. * Mnenomic Pattern: A_Electrons>rate * Variable Parent: A_Electrons_Rate_TS_Parent PT1M ° 0.0174532925>rad Spherical RTN TimeSeries Clock Angle F6.1 -180.0 180.0 LinearScale -180.0 180.0 -1.0e+31 Scalar Magnitude DirectionAngle.AzimuthAngle Velocity Roll Angle, the angle between nominal and actual ram directions Time series defined by using: EPOCH Roll_Angle The roll angle corresponds to the angle measured in right-handed sense and in RTN coordinates between the spacecraft positive X-axis direction and the positive T-axis.
