WoW: the Week of WEAVE
Description and Aim
WEAVE is the next-generation wide-field survey facility for the William Herschel Telescope. It consists of a multi-object fibre spectrograph and integral field units (IFU) with a large field of view that can obtain 1000 spectra simultaneously. The WEAVE Galactic Archaeology survey (WEAVE-GA) is the survey focused on the Milky Way, as a complement to the Gaia space mission. To further develop the GA implementation plans of the four components of the survey, and allow hands-on working time for the sub-survey teams, the Week of WEAVE (WoW) will be organized around common sessions and parallel working time. We expect that by the end of WoW, a close-to-final target selection function and footprint definition will have been achieved for the four WEAVE-GA sub-surveys and that major steps will have been taken towards the smooth integration of the GA survey within the WEAVE operation and dataflow (Survey Working Group, Core Data System, Advanced Data System, and Weave Archive System). The following topic will be discussed and/or worked on:
· Review of plans for the four WEAVE-GA sub-surveys & updates, open issues;
· Gaia data for target selection and early WEAVE science (Gaia DR1 archive tutorials, assessment of Gaia DR2 data readiness/issues for our purpose, mitigations, etc.);
· Building up a first target selection function for the four WEAVE-GA sub-surveys;
· WEAVE LR and HR expected performances for GA: WEAVE Core Processing System (CPS: data reduction) and Advanced Processing System (ACS: classification and analysis), including strategies for sky emission, continuum and telluric absorption corrections, and performances for stellar parameters and chemical abundance determinations;
· GA foreseen “typical uses” of the WEAVE Archive System (WAS).
The last day of the week will be devoted to a meeting of the WEAVE
Survey Working Group (SWG) which has a variety of responsibilities for the
whole WEAVE survey.
