Full VAST survey

The full VAST survey commenced in December 2022 and consists of 329 fields covering almost 10,000 sq deg. The survey is split into three components, with the Equatorial and High Dec fields observed 11 times per year and the Galactic fields observed fortnightly. VAST has been allocated over 2,100 hours of observing time across the ASKAP Survey Science period.

Pilot Surveys

All VAST pilot survey data is publicly available through the CASDA archive under project code AS107. Note that you will need an OPAL account to download FITS images.

Phase I

We conducted our Phase I Pilot Survey between August 2019 and August 2020. The survey was conducted at 888 MHz and used the RACS low-band footprint as a basis. The sky coverage compared to other ASKAP pilot surveys is shown below (the VAST footprint is outlined in aqua).

Phase II

In 2021 we ran the second phase of our pilot survey consisting of 2 epochs in the low band (same footprint as Phase I) and 3 epochs in the mid band, following the RACS-mid footprint.
