Additional Information : FOV: 200 um SPAD limits FOV to 60";
IRIS allows FOV down to 40" for daylight
Return Rate is always maximized; up to 2000
photons per return are allowed and handled
by the TWC circuits; at higher levels,
increasing pre-train returns cause automatic
offset tracking via software. The Event Timer
replaced the Counter Cluster
(1xHP5370A, 3xSR620). Actual SPADs are changed
frequently for tests. Rise time is for
the compensated output. The event timer
verniers are made by Dassault with add ons
from Graz.

Date Removed : 2002-12-10 00:00
Additional Information : In 2002-06-10, the travelling baro from
RGO was in Graz at that time, the Graz
