. Next: Generation from In-Orbit Data Up: EPN_ADUCONV Previous: Description Contents . Ground calibration data obtained from extensive measurements of X-ray emission lines and synchrotron lines (mainly flat fields). The gains of the individual readout nodes are derived by comparing the positions of the CTE corrected calibration lines (in ADU) with their energies. Michael Smith 2011-09-20
