Host Galaxy Association for DIAObjects

  • Melissa Graham


This document argues that, in order to better enable extragalactic transient science with brokers, two new DIAObject catalog elements should be computed and included in the alert packets: (1) the objectId for the three Object catalog galaxies with the lowest separation distance (based on the galaxy’s 2D luminosity profile) from the DIAObject, and (2) the separation distances for those three Objects.
