The TII Raw And Corrected Imagery / Spectra (TRACIS) datasets and release notes are available from ESA. The TISL1B dataset contains raw TII imagery as well as gain-correct images processed according to the EFI onboard algorithms. The TISH1B dataset contains column sum spectra at 2 Hz. For each dataset, the most probably ion kinetic energy per pixel is estimated using TII sensor simulations. TRACIS was developed at UCalgary under contract to Swarm DISC.

Example of TRACIS high-resolution (2 Hz) detector column sum spectra.
