EVLA/VLBA/GBT Resources

NRAO Interactive Services Modification Request 1 T2 2010



1. Introduction

Any changes to the telescope specific resources

2. Background

3. Requirements

  • EVLA - the following changes
    1. Add 4-band 400cm receiver and add a pop-up message when it was selected saying something like: "Bandwidth for 74 MHz is currently under test."
  • VLBA - maybe some minor changes.
  • GBT - the following changes:
    • MUSTANG
      1. Add a parameter that selects either "MUSTANG64" or "MUSTANG100 (Shared Risk)".
      2. Change the text to:
        • MUSTANG64 is a bolometer array with 64 pixels operating with a 18 GHz bandwidth centered at 90 GHz. MUSTANG100 is functionally equivalent to MUSTANG64 except with 100 pixels, a predicted sqrt(2) better sensitivity, and a slightly smaller field of view (35 arcsec instead of 42 arcsec). *MUSTANG100 is shared risk and should only be selected if the higher sensitivity is necessary. Please contact Brian Mason (bmason@nrao.edu) for more details and collaboration information.
    • KFPA
      1. Removed "Shared Risk".
      2. Change https://safe.nrao.edu/wiki/bin/view/KPAF/2010Call to https://safe.nrao.edu/wiki/bin/view/KPAF/2011Call.
      3. Add the following modes:
        • 1 beam, 4 spectral windows, 2 polarization, at either 12.5 MHz or 50 MHz bandwidth
        • 1 beam, 4 spectral windows, 2 polarization, at either 200 MHz or 800 MHz bandwidth
        • 2 beam, 4 spectral windows, 2 polarization, at either 12.5 MHz or 50 MHz bandwidth
        • 2 beam, 2 spectral windows, 2 polarization, at either 200 MHz or 800 MHz bandwidth

4. Design

Technical lead should provide a brief description of how this will be implemented in the code.

5. Deployment Checklist

Documentation? Systems/hardware/networking things needed for deployment?

6. Test Plan

6.1 Internal Testing

6.2 Sponsor Testing

6.3 Integration/Regression Tests


Signatures

APPROVED: I acknowledge that my request is fully contained in this MR, and if the Open Sky (or other NIS or PST developers) deliver exactly what I specified, I will be happy.

ACCEPTED: I acknowledge that I have validated the completed code according to the acceptance tests, and I am happy with the results.
