As a first release of simulated data, we make here available a new set of Herschel simulated data. They carefully mimics the quality, size and depth of the Herschel images in GOODS-S at 100,160,250,350 and 500um. They are optimally designed to test Herschel source extraction .

These simulations were produced as follows:

  1. For each MIPS/24um-detected (F24 > 20uJy) source, we derived its far-infrared flux densities at 100,160,250,350 and 500um following the approach presented in Leiton et al. (2014, in prep). The position and flux densities for all the 24um-detected sources are included in the catalog ‘’ (and in ASCII format: list_24um_priors.tbl
  2. Using the coordinates from the MIPS 24um map (dubbed as RA and DEC in the catalog), each source was injected into the noise map by convolving their flux densities with a PSF model based on the asteroid Vesta and a Gaussian PSF model, for PACS and SPIRE respectively. A random astrometric error around the mean astrometry uncertainty, ~0.425″ in RA and 0.421″ in DEC, was also introduced to the source positions.
