Started testing detector 4 again.
Fake stop time
Found some double pulsing out of the discriminator that was 100 ns later in time causing a second peak other than the expected one at 400 ns.
Below is a picture of a double pulse
Below is a picture of the typical 400 ns fake stop pulse that should appear as a second hit in the Multihit TDC.
