CDEV Monitoring

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

Data Files

  • Yellow and Blue FY06 average flattop measurements for a fill
  • Yellow and Blue FY06 CNI measurements summary files

Plots

polarization as a function of time: February/March: Yellow Blue April: Yellow Blue May: Yellow Blue

X-asymmetry as a function of time: February/March: Yellow Blue April: Yellow Blue May: Yellow Blue June: Yellow Blue

Yellow/Blue X-asymmetry (flattop/injection):

Yellow X-asym time dependence for a given fill

Blue X-asym time dependence for a given fill Yellow Polarization time dependence for a given fill Blue Polarization time dependence for a given fill

File Format

The linked data files include the following information.

  • yellow_summary.dat and blue_summary.dat

    month, day, year, hour, minute, second,fill,runid,timestamp,x , errx,pol, errpol, energy, statusA, statusB,x90, errx90, x45, errx45,y, erry, ana, errana,cni_time, raw_time,starttime,stoptime,flagA

    flagA: 99 - ok, != 99, not ok, not found in other dat files

  • yellow_fill_average.dat and blue_fill_average.dat

    runid, x, errx, polarization, err polarization

Selection Criteria

  • time after 1/1/06
  • RHIC P bit > 0.
  • 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.
  • The files contain the complete information starting from fill 7497.

Error Codes

  • 0: x==0
  • 6: runid<6800
  • 7: error x > 5 || errorx < 0
  • 8: fabs(x) > 15
  • 10: ana<5 || ana>20
  • 12: energy<0 || energy > 250
  • 14: fabs(statusA) > 100 && statusB!=26
  • 19: errana < 0
  • 20: fabs(pol) > 75
  • 22: month < 2 || year!=6
