CXO Project Science: MSM Animations

Table of perigee day and the time of the MSM run closest to perigee, for the 8 perigee passes during which ACIS was not protected and for the day-286 "event". The next columns are the estimated log of the peak proton spectral intensity --- p/(cm^2 sr^1 MeV^-1) at 0.1 MeV --- for -2h, -1h, 0h, +1h, and +2h from perigee, followed by the average for these 5 hours nearest perigee. The final 2 columns compare the MSM peak with the AP8MAX peak, the former being the log of MSM/AP8MAX, the latter being MSM/AP8MAX.

Short animations, accessed by selecting thumbnail gifs, comprise 1-hour intervals per image and extend no more than about 8-hours from perigee. Long animations are 15-minute intervals per image and include the full dataset as generated by Terry Onsager ( NOAA/SEC):
