=====Antenna Selection=====

Selected the best from the on/off observations: 1a,1f,1c,2a,2b,2h,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...

  - First: inform all that you are using the array" 'setalarm "Jonathon is using the array"' 
  - Identify what antennas you wish to use
  - Type the command "antgroups" to see the current antenna groups assignment
  - 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.
  - Type the command "antgroups" to verify your antennas moved to the bfa group.
  - Track a target and tune: "pointshift w3oh 1667.0 0 0"
  - Remember to move the antennas back to the none group: "antreserve bfa none 1a 1b"
  - Type the command "antgroups" to verify your antennas moved back to the none group.
  - When done, park the antennas to the default position: "park"
  - 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======

This section is to run the server side and FPGA configuration software to take a simple observation.

While waiting for the storage server to be populated and configured, dsa-ata-1 has the local 8TB disk mounted in ~dsa/data for recording. The main .fil files will be stored here. The log files for data capture will be stored in ~dsa/vikram/scratch

This will capture data from the antenna in SNAP1. 

   - Login into dsa-ata-1 (username: dsa)
   - run ~dsa/usr/DSA-10/scripts/setup_singleFil.py create
   - run ~dsa/usr/DSA-10/scripts/setup_singleFil.py start

when ready to start the observation run:
   - ~fpga_control/dsa_ata_incoherent.py

when ready to stop the observation run:
   - ~dsa/usr/DSA-10/scripts/setup_singleFil.py stop
   - ~dsa/usr/DSA-10/scripts/setup_singleFil.py destroy
   - ~dsa/fpga_control/dsa_ata_stop.py

To capture data from all 10 SNAPs:
   - run ~dsa/usr/DSA-10/scripts/setup_multiFil10.py create
   - run ~dsa/usr/DSA-10/scripts/setup_multtiFil10.py start

when ready to start the observation run:
   - ~dsa/fpga_control/dsa_ata_incoh_multi10.py

when ready to stop the observation run:
   - ~dsa/usr/DSA-10/scripts/setup_multiFil10.py stop
   - ~dsa/usr/DSA-10/scripts/setup_multiFil10.py destroy
   - ~dsa/fpga_control/dsa_ata_stop.py

After an observation, use "filedit" to correct the start frequency and start time of the data in the filterbank file. E.g.: "filedit -T 58659.932 ./slog_57929.920.fil" and "filedit -f 1680 ./slog_57929.920.fil"

If the FPGAs have been power cycled and need programming:

   - cd ~dsa/fpga_control/bofs
   - source ~jackh/venv/cfpga/bin/activate
   - ipython
   - import casperfpga
   - fpga = casperfpga.CasperFpga('dsa-ata-snap-1')
   - fpga.upload_to_ram_and_program('dsa_ata_v3_2019-06-21_1131.fpg')

repeat for each SNAP (2-10). 

=====Status Sep 19, 2019 =====

All systems were working, however seem to have developed a fault with netboot. Debugging is ongoing. It may be necessary to install a local OS on each server.
