  A detailed analysis of Herschel-PACS observations at the North Ecliptic Pole
is presented. High quality maps, covering an area of 0.44 square degrees, are
produced and then used to derive potential candidate source lists. A rigorous
quality control pipeline has been used to create final legacy catalogues in the
PACS Green 100 micron and Red 160 micron bands, containing 1384 and 630 sources
respectively. These catalogues reach to more than twice the depth of the
current archival Herschel/PACS Point Source Catalogue, detecting 400 and 270
more sources in the short and long wavelength bands respectively. Galaxy source
counts are constructed that extend down to flux densities of 6mJy and 19mJy
(50% completeness) in the Green 100 micron and Red 160 micron bands
respectively. These source counts are consistent with previously published PACS
number counts in other fields across the sky. The source counts are then
compared with a galaxy evolution model identifying a population of luminous
infrared galaxies as responsible for the bulk of the galaxy evolution over the
flux range (5-100mJy) spanned by the observed counts, contributing approximate
fractions of 50% and 60% to the cosmic infrared background (CIRB) at 100
microns and 160 microns respectively.
