ConclusionsP Current level <strong>of</strong> precision is adequate for trending if doneat greater frequency! 12 times per year (that’s successful collections)! Onboard systems provide better frequency andprecisionP Improvement in precision allows trending with fewercollections per yearP Once precision is reduced, then it is possible todetermine biases! Cross-comparison work gains further confidence! Apply approach to a greater number <strong>of</strong> data setsP These types <strong>of</strong> data sets as well as others (lunar view,additional sites) will be critical over the next 12-24months to evaluate the onboard calibrators and crosstalkcorrection s<strong>of</strong>tware
