Notes.

^(a)

SPT name: SPT-CLJ0615-5746.

^(b)

Masses published in the SPT catalogue (Bleem et al. 2015).

^(c)

The Obs. ID in bold refers to the longest observation.

^(d)

The exposure times reported in normal and bold refer to the merged datasets and the longest Obs. ID, respectively. The former and latter were used for point source detection and flux measurement, respectively.
