Opening a Window of Discovery on the Dynamic Universe

Deep Drilling Fields

 

In addition to LSST’s 18,000 deg2 main survey via its “universal cadence,” up to approximately 10% of LSST observing time will be dedicated to other programs, including intensive observation of a set of Deep Drilling Fields. Deeper coverage and more frequent temporal sampling (in at least some of the LSST’s ugrizy filters) will be obtained for the Deep Drilling Fields than for typical points on the sky. The full Deep Drilling Field program will address a broad range of science topics, including Solar System, Galactic, and extragalactic studies.

The LSST Project expects to issue a call for for Deep Drilling Field White Papers around December 2017, to be due around April 2018. A subsequent call (~Oct 2018) is expected for minisurvey proposals, due around February 2019.

Resources posted on this page will inform the Community of issues related to LSST Deep Drilling fields. 

The table below lists the four selected fields with approximate field center positions. Each field is approximately circular with diameter 3.5 degrees. Some observational dithering will likely be used (both in position angle and boresight location) to fill in CCD gaps, aid with artifact removal, etc. The details of the observing strategy are yet to be determined, including dithering and total number of visits.

Financial support for LSST comes from the National Science Foundation (NSF) through Cooperative Agreement No. 1258333, the Department of Energy (DOE) Office of Science under Contract No. DE-AC02-76SF00515, and private funding raised by the LSST Corporation. The NSF-funded LSST Project Office for construction was established as an operating center under management of the Association of Universities for Research in Astronomy (AURA).  The DOE-funded effort to build the LSST camera is managed by the SLAC National Accelerator Laboratory (SLAC).
