Antenna Selection

Selected the best from the on/off observations: 1a,1f,1g,2a,2b,3l,4g,4j,4k,5c

Note that 1k may be a candidate. But it just got fixed (burned out cable inthe feed box) and we need to review the recent results. JR - Feb 23, 2019

As a reference, here is the antenna map:

ATA Control Tutorial

This section is for Jonathon and others to allow them to control the ATA for observing purposes.

NOTE: You need to be on the NSG head node computer…

  1. First: inform all that you are using the array“ 'setalarm “Jonathon is using the array”'
  2. Identify what antennas you wish to use
  3. Type the command “antgroups” to see the current antenna groups assignment
  4. Move your antennas into the bfa group, example: “antreserve none bfa 1a 1b”. Note that you make see an error “1a 500: Internal Server Error ”, ignore it.
  5. Type the command “antgroups” to verify your antennas moved to the bfa group.
  6. Track a target and tune: “pointshift w3oh 1667.0 0 0”
  7. Remember to move the antennas back to the none group: “antreserve bfa none 1a 1b”
  8. Type the command “antgroups” to verify your antennas moved back to the none group.
  9. When done, park the antennas to the default position: “park”
  10. Important: inform all that you are finished with the array” 'setalarm “Jonathon is finished with the array”'

The command ataasciistatus will show you the status of the dishes.

Array usage needs to be coordinated with cecile Mackay cecile.mackay@sri.com, elin Klaseen elin.klaseen@sri.com and JR.

Commands

Status March 03, 2019

Got the equipment installed. We have everything except

  1. The power supply for the Valon, it has been ordered. For now we moved over theSG380 Signal Generator.
  2. We need 6 more SMA cables. So we have now 7 SNAPs connected to feeds.
  3. The fiber to connect the SNAPs and computers have not arrived. Using copper cables instead temporarily.
