DES Science Server

The DES Science Server is an image and catalogue data visualisation service developed as part of LIneA's contribution to the Dark Energy Survey (DES) survey.

The DES Science Server consists of independent microservices to meet different demands. For each of these microservices, a more flexible and modern version is being developed to provide access to LSST project private data for members and public data from various surveys for the entire community, all in one place (see details about the new visualisation services Sky Viewer and Target Viewer on the Scientific Platforms page). Its initial version remains available and provides access to DES DR2 images and tabular data.

Sky Viewer

Offers panoramic display of DES images, combined to form a single image limited only by the footprint edges, as well as maps in HEALPix format.

Target Viewer

Tool to visualise and manipulate images from a previously defined list of objects (targets). Allows ranking images, applying filters based on object properties, and creating mosaics with multiple images.

Tile Viewer

Provides visualisation of DES images with display based on Tiles, the area unit adopted by the survey. The Tile Viewer was widely used for inspection and validation of data during periods preceding internal and public data releases.
