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
