Blending Workshop 6 - Clues About Blending in the LSST Object Catalog

  • Posted on: 14 May 2018
  • By: ferguson

The goal for this session is to encourage further discussion about the fields in the object catalog (as currently envisioned, or as part of a wish list) that might be used to:

  • identify potentially unrecognized blends,
  • distinguish complex sources, such as mergers, from blended objects,
  • find large-scale, low surface-brightness features that might masquerade as background,
  • assess possible contamination from identified neighbors, for photometry or shapes.

Please contact the session organisers if you would like to contribute a talk to this session

Participants are encouraged to review the Data Products Definition Document, section 4.3.1 in particular and consider how one might use queries to find objects of interest or concern.
