The events are in the instrument level ITL. # Times are relative to the Lutetia Closest Approach. # NOTE: The start of scientific data acquisition is the first mode change to # CTS/DualC, even though it will be Dark Sky for the initial 3+ hours. # The estimated time of acquisition of signal = CA - 5 hours. Version: 00001 Ref_date: 01-Jan-2000 # Irrelevant because will be overridden by top-level ITL, but needed for ORFA.
