CLAS G6B Data Cooking

Pass0.0

• Quality of DC Calibration based on Pass0 data
  
  Run 19341 and 19700 were calibrated with many efforts. Using their parameters 19 runs have been checked.
  
  I. Residual resolution
  II. Hits per TBT
  III. chisquare of fits
  
  
• DC Calibration have been done for 16 runs(before Pass0):
  
  19743(a, b), 19740(a, b), 19737(a, b), 19740(a, b),
  19711(a, b), 19694(a, b), 19672(a, b), 19660(a, b),
  19583(a, b), 19541(a, b), 19514(a, b), 19496(a, b),
  19476(a, b), 19425(a, b), 19392(a, b), 19341(a, b).
  
  Click on 'a' and 'b' inside the parenthesis and check the quality of the calibration. Here the 'a' means after the first time DC calibration and 'b' means before.
  
  
• Some recooking data after the DC calibration could be found at:
