Calibrated JEDI data users are reminded to pay close attention to the species and energy range information in the headers of the calibrated (L3) data files.  The contents of a given named "channel" can change over the mission lifetime.  The correct information can always be found in the data file headers or the PDS labels.

While this information is mentioned in the JEDI SIS document, it was felt that a special note was appropriate following the 2024 upload of new lookup tables to the JEDI instrument.

Prior to day 2024/110 (April 19, 2024), the high energy resolution TOFxE channels contained proton counts and the TOFxE non-proton channels measured heavy ions. Keep in mind these are distinct from the JEDI TOFxPH channels.  To expand the coverage of heavy ions after day 2024/110 only, we have re-programmed the binning of the counts or "channelization" on the spacecraft but continued to keep the names the same for sw purposes. Therefore after day 2024/110, high energy resolution TOFxE will contain heavy ion data and "non-proton TOFxE data" will be pure protons. 

As a reminder, the SSD-only channels, either the bare detector ion channels and the slightly shielded electron SSDs are typically electron-dominated at Jupiter.  The two SSD channels, A180-T1-small-pixel-ions and A180-T3-small-pixel-ions are the so-called "witness" detectors and are described elsewhere.
