revised VLASS proposal

All, Based in part on discussions about what is the appropriate scope of the VLASS and comparisons with optical surveys, there is some thought being given to "simplifying" the VLASS. One of the suggestions that has been floated is that the entire GALACTIC component of the VLASS be simply e...

Re: Galactic counter proposal

Thinking ahead to the actual proposal, what do we need? Using a couple of examples from ones that people have posted, I could imagine a structure such as the following. Section: Galactic Science Enabled by the VLASS The Galactic component would consist of H hours focused on the area ... in the A con...

Re: where we stand

I'm curious about the root of the GMRT question. Wouldn't comparison with GMRT hold for the entire VLASS, not just Galactic coverage? I don't know realistic GMRT performance numbers, but in the GMRT manual they say 30 microJy/beam is the best L-band performance *ever* achieved, which I assume means...

Re: where we stand

In B config, my experience with lots of novae in the Galactic plane at L and C bands implies that we should easily be able to hit thermal noise. In the more compact configs, I often have to exclude the shortest baselines, but we should be in the clear with B confg. That's re-assuring news. That's n...

Re: Impact of surveys, impact on peer-reviewed science

Another approach, fraught with the usual uncertainties. I asked ADS to return peer-reviewed papers published in 1995 or later, sorted by citation count. Of the top 100 papers #22. NVSS paper #94. first FIRST paper (1995) Other than WMAP papers, the only other "radio astronomy" papers to cr...

Re: Galactic WG Summary so far (comments please!)

Following up on Laura's post, I've been trying to figure out the answer to her question as well. It seems to me that there are two answers: 1. CORNISH exists. Thus, a 5 GHz Galactic plane component of the VLASS would have to argue that the increase in sky area and depth is sufficient to justify some...

Re: Keep an eye on the EWG discussions

Following up on Steve's suggestion, here's what's currently being discussed in the Extragalactic WG: a three tiered survey with the following structure DEEP to a depth of ~ 1.5 microJy/beam over 10 deg^2 WIDE to ~30uJy over 3600 sq. deg. ALL-SKY to ~100uJy over ~30k sq deg. (excluding the WIDE area)...
