* Applied Fiducial cut ( see Profile YZ on this wiki.) and time difference [#tfa1a6e9]
-(dcZ - 15) ^2 + dcY < 2500
- mcpresult_timemcp[0] - scinthit_timescint[0] > 0,
-mcpresult_timemcp[0] - scinthit_timescint[0]<40.

* Applied additional cut; zdiff(mcp-dcZ) < -10 && zdiff(mcp-dcZ) > -25 and time cut[#y619b8fc]
- Main structure in MCPZ - DCZ scatter plot were selected.
- second peak in time difference spectrum is cut.

Minimizer is Linear
Chi2 = 89351.9
NDf = 10123
p0 = -16.4248 +/- 0.0305098
p1 = 0.0292232 +/- 0.00425457
*Z offset MCP and DC [#q1009eec]
-DCZ's zero is on the system Z-zero point + 15mm.
-(2011.2.19)According to previous study, MCP has ~1mm shift along with Z direction.
-(2011.3.1)DCZ - MCPZ -18mm is the best estimated offset
*Slope cut [#k8ad19bc]
-Slope distribution: without any cut( of cource, isGoodDC and ntdcmcp[0]>1 is applied. It is a result of analysis of skimmed data)
**no cut [#s4a14abd]
