Rule #1: The key time period for balancing SI mode statistics is the 6 month Epoch By the end of the epoch, the SI mode statistics should match the rules stated below. Rule #2: Each of the three, default, 6 chip, SI modes (or their 5 chip equivalents) must be used at least once in each load week. - If two SI modes are lagging in either cold time or total time, apportion the week's ECS measurements between the two of them roughly commensurate with the amount they are lagging. - The 6 month Epoch allows "even" correction of two lagging SI modes. No need to pile a weeks worth of ECS measurements on one SI mode if two are lagging. Rule #3: Make certain to spread the amount of COLD ECS time as evenly as possible across all three SI modes Balance Cold measurement data between the three default 6-chip modes within 10% of each other on an Epoch basis
Rule #4: Spread the amount of *Total* ECS time as evenly as possible across all three SI modes.
- Balance Total measurement data between the three default 6-chip modes within 10% of each other on an Epoch basis.
Rule #3 takes precedence over Rule #4.
Rule #5:At least 60% of scheduled ECS measurement time must be -118.7degC
Rule #6: Any ECS measurements during a Perigee Passage that are cold MUST be assigned to the nominal ECS run SI modes. i.e. Any requested Rawmode runs can be done with a warm focal plane.
