SEDs of the cold debris disk source candidates for which the submm flux limits are substantially below the extension of the single temperature blackbody fit to the IRAS excesses – HIP 51658, HIP 68160, HIP 76375 and HIP 112460. The NextGen atmospheric models corresponding to the best-fit stellar photosphere and the blackbody fit are plotted. The optical-near IR photometric points (black points) have been compiled from Tycho2 and 2MASS. The mid-IR photometric points have been drawn from WISE (dark blue points). For HIP 51568, with Herschel PACS photometry, the orange points with downward arrows correspond to the source 3σ upper limits. The orange points represent the cumulative flux density of three nearby contaminating objects. For HIP 76375 and HIP 112460, with Spitzer MIPS photometry, the green points represent the source flux density and green points with downward arrows represent the source 3σ upper limits. The flux density of the contaminating object measured in the MIPS 70 μm image for HIP 76375 is represented by the light-blue point. The CSO submm flux upper limit at 350 or 450 μm are represented by the pink points with downward arrows.
