9mm secondary focus receiver (30-34 GHz)
This is a 7-beam system with linear and circular polarized feeds. It is usable for continuum observations and - in a limited way - for pulsar observations.

Comments:

  • The gain curve was corrected for opacity.
  • If no other information about the opacity is available a typical zenith tau value of about 0.05 for good weather conditions can be assumed.
