Solar Orbiter Level 3 data

Consist of daily CDF files containing the following data variables:

• Ion_Flux_{S,A,N,D}: Ion intensities in 31 energy bins for each field of view (S: sun, A: anti-sun, N: north, D: south). Mostly protons, but other ion species may also be present.
• Electron_Flux_{S,A,N,D}: Electron intensities in 16 energy bins for each field of view. May be affected by contamination from protons around 500 keV.
• Electron_Corrected_Flux_{S,A,N,D}: Electron intensities in 16 energy bins for each field of view corrected from ion contamination.
• Pitch_Angle_{S,A,N,D}: Pitch angles of the 4 fields of view with respect to the average magnetic field.

The CDF also contains statistical uncertainties for all the data variables along with ancillary data regarding the spacecraft orbital position and orientation.

Includes 3 panels, from top to bottom:

• Time-series plot of the electron intensity (corrected from ion contamination) for all four EPT telescopes (sun, anti-sun, north, south).
• Electron intensity vs pitch angle combining STEP and EPT. Data from STEP is included only for periods with high enough electron flux (indicated by a horizontal bar below the panel). An empirical cross-calibration factor (1/1.25) between STEP and EPT is applied to STEP data.
• Pitch angle coverage for all four EPT telescopes.

Includes 3 panels, from top to bottom:

• Time-series plot of the proton intensity for all four HET telescopes (sun, anti-sun, north, south).
• Proton intensity vs pitch angle.
• Pitch angle coverage for all four HET telescopes.

All flux values are GROUND CALIBRATED data in units of 1/(cm^2 sr s MeV) and averaged to 2-Minute-Mean values.

The flux is given in four viewing directions, indicated by prefixes Side0_, Side1_, Side2_, and Side3_ in the column names.

Noisy periods and periods with significant packet loss between the instrument and back-end electronics were removed.

These data were calculated using the results of the so-called bow-tie analysis, which means that the fluxes are given at an effective energy of the channel. This approximation works well only when the energy spectrum of the particles is a decreasing function of energy.
