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
