  • We Describe The Data Processing Pipeline Employed By The Low Frequency Instrument (Lfi) Data Process
  • 5 Months Of Operations At 30
  • 44 And 70 Ghz
  • In Particular
  • We Discuss The Various Steps Involved In Reducing The Data
  • Starting From Telemetry (Tm) Packets Through To The Production Of Cleaned Calibrated Timelines And C
  • Data Are Continuously Calibrated Using The Modulation Induced On The Mean Temperature Of The Cosmic
  • Sky Signals Other Than The Dipole Are Removed By An Iterative Procedure Based On Simultaneous Fittin
