Pilatus 2M. This is the histogram of a random frame I picked:
counts number
0 2211457 thus 97% of all pixels have zero counts
1 65154 that's 2.8% of all pixels
2 2107
3 96
4 20
5 12
6 3
7 5
9 2
10 2
11 3
12 4
14 2
15 1
29 1
all other counts are zero. The average count is 0.03. Processing was done with
the March-2015 version of XDS; older versions do not work well with average
counts below about 0.5 .
best,
