Title: IBEX-Lo Interstellar Neutral Histogram Counts and Direct Event Counts

Interstellar neutral (ISN) histogram and direct event counts for each of the 60 IBEX-Lo angular bins. The data includes start and end times for each 512 spin period in GPS time as well as total accumulation times. Data files are in CSV format and are labelled according to their IBEX orbit and orbit arc.

Data are collected for periods within the ISN goodtimes:
	
	-Accumulated direct event data must meet the following criteria:
		1. Golden triples
		2. “Hydrogen” time-of-flight
		3. Energy Steps 1-3 are included during non-special mode 			   periods.



ISN data product QA checks:

	-All ISN season orbits are checked for contaminating backgrounds 		 around the ISN peak itself.  Times with high backgrounds are 			 eliminated.
		-Background threshold for this test is determined orbit by 			 orbit using sample quiet times.  
		-Times when the TOF 2 rate exceeds this background by 60% 		 are excluded.
		-Times with spin issues are excluded
		-Times with special operations are excluded (gain tests, 		 etc…)

	-Remaining times are included in ISN data products

	-Resulting ISN data products are checked for continuity (time and 	 angle), and suppression (loss of direct events due to instrument 		 throttling).
