  2. INDEX • FIRST RESULTS • CUT 500 ADU • THE BEST RESULTS - SIGNALS RW AND RWM - RESIDUALS RW AND RWM • LANGAUS FIT • ALL RUN 2169 • CONCLUSION

  4. FIRST RESULTS USED CHRISTIAN JULIA FILES PROBLEMS A LOT OF HITS IN 1º DETECTOR WE HAVE 1º Y 2º DETECTOR WITH SEED < 500 EXPLICATION PRAGA PEOPLE NOISE

  5. PROBLEM SEED < 500 ADU Seed Cluster 3x3 Cluster 5x5

  6. CUT 500 ADU AND ROI IN CENTRE ALL MATRIX -DELETE PEAK < 500 ADU - CoG = FULL - SIZE CLUSTER = 5 X 5 - Take as REGION OF INTEREST (ROI) the central part of thematrix in all detector

  7. THE BEST RESULTS WITH BADPIXELMASKINGALGORITHM=NOISEDISTRIBUTION COMMON MODE ALGORITHM = RWM OR RW HITREJECTIONCUT =7 CLUSTERINGALGO = FIXEDFRAME FFCLUSTERCUT=2.6 FFCLUSTERSIZE(X,Y)= (5,5) FFSEEDCUT=7 INSIDEREGION = ( ALL 7 7 57 249) SEEDMINCHARGE= (500 500 500 500 500 500 ) CLUSTERTYPESELECTION = NXMPIXEL=3X3 [“ONLY SINGLE PIXEL”] TELESCOPERESOLUTION = 5 CHI2XMAX=10 “ONLY RUN 2169-000.dat DUT H3.0.04 => we only have used one partition.”

  8. SIGNALS RW H3.0.06 BAD =12 H3.0.16 BAD =3 DUT H3.0.04 BAD =0 H3.0.012 BAD =8 H3.0.11 BAD =0 H3.0.010 BAD =130

  9. SIGNALS RWM H3.0.06 BAD=4 H3.0.16 BAD=3 DUT H3.0.04 BAD=0 H3.0.012 BAD=0 H3.0.11 BAD=0 H3.0.010 BAD=130

  10. RESIDUALS RW

  11. RESIDUALS RWM

  12. GAUS FIT BETWEEN (-3 3) RWM

  13. IS THIS FIT GOOD ?

  14. WE GET SIMILAR RESULTS WITH ROW WISE AND ROW WISE MEDIAN BUT WE USE RWM IN THE NEXT SLIDES

  15. SIGNALS ALL RUN 2169

  16. RESIDUALS ALL RUN 2169

  17. LANGAUS FIT H3.0.04

  18. CLUSTER SINAL 3X3 LANGAUS FIT H3.0.04

  19. CONCLUSION WE DON´T KNOW IF THE RESIDUALS ARE GOOD. WE THINK THE RESIDUALS OF DUT (D2) ARE BAD, IT IS HIGH IN X AXE
