The Level0 photon files contain the same photon event data as the raw MeDDEA binary data, but converted to FITS format for more convenient analysis. Each raw photon data file generates a single Level0 photon FITS file. The photon product is an on-demand X-ray photon list that is generally available during large flares and calibration periods. Level0 photon files contain event data from detector triggers, including packet-level timing information and science event information such as detector identifier, channel, clock value, and uncalibrated event energy in ADC counts. These data support investigations of the directivity of solar flare hard X-ray emission and the angular distribution of flare-accelerated electrons.
