Liang, Mengning Tue 2/28/2017 4:09 PM To: Dubrovin, Mikhail; 148 – double hit in equator – 3 peaks 162 – no peaks 525 – double hit in equator - 6 peaks 1456 – should find multiple arc peaks 1521 – double hit equator – 4 total peaks 2551 – no peaks I could not find parameters to find the right peaks in these events – can see by eye where the peaks are. Thanks, Meng |
