CDEV Monitoring

(Archived into Drupal from MIT servers in August 2008. Original analysis by Julie Millane and Bernd Surrow.)

Data files

  1. Yellow and Blue FY05 CNI measurements
  2. Yellow and Blue Average X-asymmetry and polarization (flattop)
  3. Yellow and Blue FY05 CNI measurements reduced
  4. Yellow and Blue FY05 CNI measurements complete

Selection Criteria

  1. time after 4/1/05
  2. RHIC P bit > 0
  3. Polarization error is calculated using both err asym and err x.  This differs from the plots which only use err x and assume that err asym = 0.
  4. The files contain the complete information starting from fill 6848. Info for fills 7263 and 7264 is missing.
