PSZSPT: a joint Planck and SPT-SZ cluster catalog

Understand

We present the first cluster catalog extracted from combined space-based (Planck) and ground-based (South Pole Telescope; SPT-SZ) millimeter data.

• We developed and applied a matched multi-filter (MMF) capable of dealing with the different transfer functions and resolutions of the two datasets.
• We verified that it produces results consistent with publications from Planck and SPT collaborations when applied on the datasets individually.
• We also verified that Planck and SPT-SZ cluster fluxes are consistent with each other.
