Checked the jitter today and it is pretty bad. The facets do not overlay each other in time.
With the current settings the pru measures a 1 percent error in time. I have been able to work with a 0.25 percent and a 0.16 percent variance in the current setup, see the constant JITTER_ALLOW in the header. However after gluing I couldn't get it back to 0.16 percent. Probably the photodiode is not hit in its sweet spot.
Below is what I hoped to measure; a nice series of dots.... The most upper dot originates from edge detection. This picture was made of a single facet.
