Descripción

Galaxy clustering is one of the main cosmological probes used by the Dark Energy Survey to investigate the nature of the Dark Energy. In order to avoid biasing our measurements derived from galaxy clustering, the impact of observing conditions must be taken into account, since they can imprint a non-cosmological clustering signal. These observing conditions are characterized through the creation of and Survey Property maps (SPs) which are used to mitigate their contamination. The aim of this contribution is to showcase how the influence of these SPs on the clustering is identified and to explain the procedure that is followed to reduce their impact.
