What observations will be taken in Science Verification, and when will the data become available? Will new SV targets be added before my Cycle 0 proposal is reviewed?

A table of ALMA Science Verification (SV) targets and observing parameters is provided at the "ALMA Data=>Science Verification" link from the ALMA Science Portal (

Two SV datasets were posted on June 1, 2011: NGC3256 and TW Hya (available from the above link). No new SV datasets will be posted before the proposal deadline on June 30, 2011. Other datasets will be posted thereafter, but there is no set schedule for the release of these data. The ALMA project will announce the availability of new datasets through email notifications to all registered users.

As quoted on the SV webpage, users are welcome to propose for SV targets during Cycle 0, although they "...will need to demonstrate that [the proposed observations] will provide new information...for example, exploiting the sensitivity and/or resolution of the ALMA Cycle 0 array or by using new frequencies, spectral configurations, etc.".

The SV table lists published observations that the ALMA data will be compared to. When writing Cycle 0 proposals for objects in the SV list, users should assume that the SV data will produce results similar to those that appear in the given references.

New SV targets and/or target parameters will be added as new ALMA capabilities are deployed and tested. However, the current table of SV targets will be in effect through the completion of the Cycle 0 proposal review process (i.e., no new targets or spectral transitions will be added during this time period).
