Version: 00001

Ref_date: 01-Jan-2000  # Irrelevant because will be overridden by top-level ITL, but needed for ORFA.

# NOTE: Actual Start_time of this sequence must be 8 minutes prior to the
# Astrd_Mode_1_StartTime in the AMRF500A command issued in Step 2, below.
# This time in turn was determined as being 00:10:48 prior to the current estimate
# of the Steins Closest Approach and is considered the Zero-point time of this ITL.
# Therefore:  Start_time = CA - 00:18:48.
# NOTE: Start_time may need to be pushed back to allow for uncertainty in CA time.

Start_time: -000_00:08:00

End_time:   +000_00:23:00
# NOTE: End_time does not include data playback time.
# Init_Mode:        MIRO       CTS_DualCntm

Description: "   | Ast.Mode requires that MIRO be in Dual Continuum mode."
Description: "   | Since this shuts off the CTS, we also need a CTS warmup command"
Description: "   | at least 5' before the start time."
