Cong Zhang shared his paper on the receiver and calibration for a 21 cm global spectrum experiment that uses a high-impedance input. Paper is attached.

Reza reviewed the near final draft of the tNCCSz paper.

Greg, Olivier, Peter went through the paper one more time. John will take a final look later today.

Our next call will be Tuesday January 6. Peter proposed that we find a volunteer to review the recent CHIME autodetection paper at this meeting. A second paper on cosmological interpretation is expected soon. Anyone interested?

There are minutes attached to this event. Show them.

  High Precision Calibration of an Operational Amplifier based High-Input-impedance Receiver in the 21-cm Global Spectrum Experiment 20m
  
  Cong ZHANG will discuss his paper, which he has just submitted to the Astronomical Journal. This calibration method is applicable to the type of high-input-impedance 21cm global spectrum receiver similar to the Jeffery Peterson's High-Z (Jeff is listed as one of the authors in this paper).
