  1. VLASS Survey Def. Options • A: Monolithic (1 tier): • S-band/B-config (BnA for dec. < -10 deg) • 31100 sqdegr. Entire sky > -30 • 54uJy (higher in the plane) Total 8800 hrs • B: Monolithic (2 tier): • Extragalactic 21500 sq. deg. (S-band/B-array) • 50uJy: 75 > dec > -10 deg. • Galactic: 2800 sq. deg. (S-band/A-config) • 30uJy: +/-5 deg (plane); l +/- 14; b +/- 10sq. deg. (Bulge) • Impact 8800 hrs over 6 years (20% usage/80% efficiency)

  2. VLASS Survey Def. Options • C: WIDE + Ku: • Extragalactic 21500 sq. deg. (S-band/B-array) • 50uJy: 75 > dec > -10 deg. • Galactic Ku-band (90uJy): l +/- 4 deg 2200 sp. Deg. (2350 hr) • Impact 8800 hrs over 6 years (20% usage/80% efficiency)
