DEEP component discussion
DEEP VLASS component range of possibilities: Min Area = 10 sq. deg (Jarvis whitepaper) Max Area = 30 sq. deg (White et al. VLA proposal) Max Depth = 1.5uJy (Jarvis whitepaper) Min Depth = 4uJy (White et al. VLA proposal) Multi-epoch: Yes. The required exposure times greatly exceed the single-epoch v...

WIDE component discussion
WIDE VLASS component range of possibilities: Min Area = 3603 sq. deg (DES+HSC) Max Area = 13055 sq. deg (LSST+DES+HSC) (see below for detailed notes) Min Depth = 50uJy (3x FIRST) Max Depth = 30uJy (5xFIRST) Min Exp Time = 30s Max Exp Time = 90s Multi-epoch: Up for discussion. These times are such th...

If you weren't at the VLASS meeting at AAS and/or haven't read the wh...

Use of Forum and Google Group
Hi all, As Gordon explained in his last email, a VLASS-type survey is still on the table, and they have set up a "Science working group" to hash out more of the details. This is currently split into several area-specific working groups, one of which is the Extragalactic working group (EWG)...

Welcome
The extragalactic group is encouraging discussions around the idea of merging the whitepaper led by Richards and the whitepaper led by Jarvis into a single VLASS proposal. Possibilities include 1) 2 tiers: medium-wide (~5k-13k sq deg @ 31-50uJy) + deep (10 sq deg @ 1.5uJy) or 2) 3 tiers: wide (full ...
