Analysis of Sector 4 performance in August 2011 Testrun

For this QA Analysis there were two sets of cuts used. One set to was used as a reference with minimal cuts set. The other one used very stringent cuts to suppress fakes. These cuts were applied for each day on two sets of data. One set consists of data from HRichHit and HTofClust, the other data are from HParticleCand for comparison.

Cut	Reference	Strict	Sector 4 Day 230
# fired pads	> 5	> 10	> 8
Tof Multiplicity	< 13	< 10
Vertex z	- 65 mm < z < 0
%$ \Theta_{Rich} + \Theta_{Tof} $%	--	> 90
%$ \Phi_{Rich} - \Phi_{Tof} $%	--	< 4
Ring Centroid	--	< 2.0
Charge p. Pad	--	> 80	--
Pattern Matrix	--	> 150	> 125
Time-of-Flight	--	6 ns < t < 8.5 ns

Charge per pad was set to > 120 for Day 230
