1. Discussion Meeting of ISSI Science Team 70
Bern, 27 to 31 March 2006.

2. Progress on cumulative particle fluences and the K-parameter

3. The K-parameter: maximum vertical deviation

4. Energy dependence of the mean K over 9 ISEE-3 periods (the periods are about 6 months long, between 1978 and 82)

5. Mean yearly K parameters and standard deviation parameters for the three lowest energy channels of the CPME instrument aboard IMP-8. The parameters were averaged over 28 years.

6. Mean yearly K parameters (over 28 years) of the IMP-8 CPME ion detectors for 10 energies, with Gaussian fit.

8. Yearly K parameters for three IMP-8 energies (high above)

9. K-parameter as a variabilty index - plots for ISEE-3 and IMP-8
(From Jim Ryan’s ICRC Rapporteur talk in Tsukuba, 2005)

10. Cumulative fluence plots for 7 proton energies of LION data for 1999 (Telescope 2, detector 1). Energy increases from left to right and top to bottom.
It is seen that the K parameter (maximum vertical distance from the diagonal) tends to increase with increasing energy.

11. Change of the mean yearly K parameter with energy for LION

12. Note the break points in both plots when the detection regime changes
