An example of the data portion of a 5 parameter list mode file looks like this
using hexadecimal:
Start of raw data field at offset 280h
P1 P2 P3 P4 P5 P1 etc.
byte offset 00000280h: A5 06 6A 0F 50 17 A4 1F 32 27 9B 86 6A 8F 4F 97
N.B.: byte order!
Cell 1 low high
---------- ----------
P1 in binary is: 10 10 01 01 00 00 01 10 or A5 00h when masked to 10 bits
which is channel 165 decimal
P2 in binary is: 01 10 10 10 00 00 11 11 or 6A 00h when masked to 10 bits
which is channel 106 decimal
Cell 2
P1 in binary is: 10 01 10 11 10 00 00 10 or 9B 02h when masked to 10 bits
which is channel 667 decimal
Why do they write more than 10 bit data? I'm sure there's some Coulter answer
in there somewhere.
