VLBI - Narrabri scheduling procedure

  • Set Averaging=10
  • Extend the first source into the setup time or schedule 1934 or 0823 first so we can run CAOBS while we set up.

  • SINGLE FREQUENCY OBSERVING
    1. Set Frequency 1 to the centre of the observing band. This also applies to 12.2 GHz methanol VLBI.
    2. Set Bandwidth 1 to the required bandwidth ( 4, 8, 16 MHz ).
    3. Set the Correlator configuration file to:
      FULL_4_1024 for 4 MHz bandwidth VLBI
      FULL_8_512 for 8 MHz bandwidth VLBI
      FULL_16_512 for 16 MHz bandwidth VLBI

  • TWO FREQUENCY OBSERVING
    1. Set Frequency 1 to the centre of the observing band. This also applies to 12.2 GHz methanol VLBI. Set Frequency 2 = Frequency 1 unless we want to do a different frequency.
    2. Set Bandwidth 1 to the required bandwidth ( 4, 8, 16 MHz ). Set Bandwidth 2 = 128 MHz.
    3. Set the Correlator configuration file to:
      FULL_4_1024-128 for 4 MHz bandwidth VLBI
      FULL_8_512-128 for 8 MHz bandwidth VLBI
      FULL_16_256-128 for 16 MHz bandwidth VLBI
