Results of the IR template fitting of our four HLS sources with the B15 dust templates and MMPZ method using the SPIRE, NIKA2, and NOEMA photometry. The plots in the first column show the probability density distribution (normalized by the peak values) of each source. The second column shows the evolution of the weighted-average infrared luminosity with redshift. The third column shows the best-fit SED models with the observations. The sources from top to bottom are HLS-2, HLS-3, HLS-4, and HLS-22.
