[gate-users] cylindricalPET

[Fernando Rannou]

That's pretty good.  I actually found that there is a typo
in the User's guide on page 96. The coincidences will be valid
if the difference in block numbers is greater than or equal to 2,
not just greater than. Because otherwise if you set to 1 you
would still not get any coincidences and a value of 0 is not
allowed.
