First Draft of VLASS Proposal Now Available

Postby smyers » Mon Sep 08, 2014 12:30 pm


The first draft of the VLASS survey proposal is now posted on the NRAO VLASS wiki at

This draft underwent some internal review and comment, and revision is currently underway based on those comments. We expect a new draft will be completed on or around October 15 and posted on the public wiki. This next version will be submitted for internal NRAO technical and science review, revised, and again posted for community comments around January 1, before finally being reviewed by an external committee. The entire astronomical community should feel welcome to submit comments on the proposal at any point during this process to this or the appropriate WG forums.

In devising this plan, the science white papers have been used and built upon to create a broad-based 3-tiered 2-4GHz high-resolution survey with all-sky, wide area, and deep field components. Although each individual tier could have made use of the full observing time to best promote those science goals, it was felt by the Survey Science Group (SSG) that a combined survey would provided the greatest impact for the widest user base.

Note that the initial draft of this proposal was written with the goal of observing commencing in late 2015. With a review now envisioned for early March 2015, upon a green-light the observing for VLASS would start no earlier than Spring 2016.

The individual SSG Working Group chairs will also be posting to the relevant WG forums regarding issues for those groups going forward.

For the SSG,

Stefi A. Baum (VLASS SSG Co-Chair)
Eric J. Murphy (VLASS SSG Co-Chair)
Claire Chandler (NRAO VLASS Director)
Steven Myers (NRAO VLASS Technical Lead)

One thing that I find missing in the draft is a detailed rationale for the choice of observing at S-band.
There are definitely arguments to that effect scattered through the text, but I think they need gathering
into one section of the proposal that will also look at the pros and cons of that choice versus a priori
reasonable alternatives, such as using the L-band in the A configuration for a very similar angular
resolution. The choice may very well be optimal, but at this stage I need convincing that it
