The PACS Evolutionary Probe (PEP, Lutz et al. 2011) is a Herschel guaranteed time deep extragalactic survey (KPGT_dlutz_1) targeting six among the most popular "blank fields", ten lensing clusters of galaxies, and two z ~1 clusters at wavelengths of 100, and 160 microns. PEP includes SPIRE observations of the two z ~1 clusters at wavelengths of 250, 350, and 500 microns. SPIRE coverage of all other fields is available from the HerMES survey (Oliver et al. 2010). In addition, deep SPIRE GOODS-N data are provided by the GOODS-Herschel program (Elbaz et al. 2011).The list of 24 micron priors adopted in the LH field belongs to a preliminary, private catalog, soon to be replaced by an official public release (E. Egami, January 29th 2013, private communication). The PEP DR1 data package includes this catalog, providing cross-IDs between the list of priors and the new 24 micron catalog soon to become public. See the documentation for more information.
