Outline

• Different data sets
• Production chain for Nano-dsts
• QA-plots for gain calculations
• Status of present status

3
Different categories data sets

• This data set is divided into following
  categories
• With beam on pedestal Beam Off pedestal
• High Voltage conditions
• -1400 Volts lt-1400 Volts
  gt-1400Volts
• a). Trigger High (Reverse Half and FulField)
• b). Trigger Low (Reverse Half and FulField)
• c). Trigger Mid (Reverse Half and FulField)
• d). Minbias

Nano-Dst Production chain

• Macros used for production

• pmd_betaProd_isc.C
• read_isc_chi2.C
• load_db_fromNT.C

Calibration constants are filled in the database
based Category Wise.

• Makers used for Production
• StMuDSTMaker
• StMuAnalysisMaker
• StPmdClusterMaker
• StMu2Maker

Basic Plots for PMD

• Total number of chain working 17 and there are
  33 chain sm combinations.

Problems faced

• Memory consumption by TCloneArray.
• How to deal with the runs taken with different
  voltage and with different pedestal status during
  one day
• Disk Space

15
Status of Nano- Dst production

• With Pedestal On SM  20 OFF, and ALL SMs in PMD
  plane -1400V except SM 24 which is at -1200V
• So far the data from day 80 to 84 has been
  analysed with Trigger High and data base for gain
  corrections has been filled.
