System temperature

june,2002

  • Daily, yearly monitoring of the system temperature for all receivers (except alfa).
  • Alfa Tsys by month.
  • nov04 thru feb05: TsysA/TsysB for alfa observations.
  • lbw Tsys for 2002.
    •    Tsys for lbw was computed using the calibration scans taken during 2002. The temperature reported is (polA+polB)/2. The data is plotted by frequency. 2nd order polynomials were also fit to the data.

  • Fitting Tsys(za) using cal on/off data (apr00-jul00)

    • TsysA/TsysB ratio not unity, 180 degree az period

  • Jun02 "polarized" Tsys vs azimuth using cband receiver.
  • Apr03: "polarized" Tsys vs az,za using lbw.
  • May03: "polarized" Tsys vs az,za using sbh.
  • Aug05:  "polarized tsys" in using the alfa receiver.
