The modeling of the Spectral Energy Distributions (SEDs) is a generally used method to characterize the so called ´´Debris Disks´´. This technique requires reliable fluxes measurements in a wide range of wavelengths including the IR and sub-mm regimen. However, fluxes at wavelength > 100 um are not always available. In this contribution we investigate how such measurements affect the derived parameters for a sample of 24 stars showing excesses in the SEDs. If the excesses at wavelength about 70 microns are larger than the excesses at wavelength > 100 um, the sets of disks parameters derived from the SED modeling excluding and including fluxes for wavelength  > 100 microns roughly agree.
