PI made separate determinations, based on looking at their higher resolution data, when they thought IMP-8 was beyond the bow shock. There was almost always, but not always, agreement. Over the past couple of years, there has been more effort to agree. The energetic particle data from IMP-8 included on OMNI is taken in the solar wind part and non solar wind parts of the orbit.
Gaps indicate missing data for that time period.
