SPT-3G Observations of Euclid Deep Field South

This page provides access to the data products associated with Archipley et al. (2025) Millimeter-wave observations of Euclid Deep Field South using the South Pole Telescope: A data release of temperature maps and catalogs.

In general, products in the SFL projection were used to create the galaxy cluster catalog (Section 7) and products in the ZEA projection were used in the emissive source catalog construction (Section 6). If you have any questions regarding these data or their use, please contact Melanie Archipley (archipleym [at] uchicago.edu) and/or Alec Hryciuk (hryciuk [at] uchicago.edu)

Please refer to the following sections of Archipley et al. for more information about the different types of products:

Temperature maps in micro-Kelvins in SFL and ZEA projections (Section 5)
Bright source thumbnail temperature maps for all bands in micro-Kelvins in the ZEA projection (Section 3.4)
Apodization masks in SFL and ZEA projections (Section 5.1.1)
Binary pixel masks in SFL and ZEA projections (Section 5.1.1) used in the cluster and source catalog constructions, respectively. Telescope beams (Section 5.1.2). The file contains the B_ells for each band (one per column).
Noise amplitude spectral densities in micro-Kelvins used only in the cluster catalog construction (Section 5.1.3) Transfer function (Section 5.1.4)
CLEAN beam maps in mJy (see Section 4.1, Section 6) associated with the emissive source catalog Signal-to-noise ratio maps (see Section 4.2, Section 7) associated with the galaxy cluster catalog Emissive source catalog (Section 6)
Galaxy cluster catalog (Section 7)
