Added thumbnails/cutouts (from SDSS DR16) for all objects in the Object table, except for ~130 objects that have no matching thumbnails/cutouts.
About
This page contains the information for the LSSTC Enabling Science: AGN data challenge as proposed by the LSST Active Galactic Nuclei (AGN) Science Collaboration in the Summer of 2020.
The DataSet
The sources included in this dataset are coming from two main survey regions: SDSS Stripe 82 (S82) and XMM-LSS. The S82 region has been redefined to maximize the overlaps with the Dark Energy Survey (DES). The footprint for these two regions are:
Stripe 82
| RA | Dec |
|---|---|
| (-60, -43] | (-1.25, 1.25) |
| (-43, 0] | (-2, 2) |
| (0, 45] | (-7, 5) |
| (45, 60) | (-1.25, 1.25) |
XMM-LSS
| RA | Dec |
|---|---|
| [34.2, 37.125] | [-5.72, -3.87] |
