The observations are conducted with IRAC in the 3.6 and 4.5{mu}m bands over an area of 7.04deg^2^, reaching 1{sigma} depths of 1.29{mu}Jy and 0.79{mu}Jy in the 3.6{mu}m and 4.5{mu}m bands, respectively. The photometric catalog contains 380,858 sources with 3.6 and 4.5{mu}m band photometry over the full-depth NEP mosaic. Point-source completeness simulations show that the catalog is 80% complete down to 19.7 AB. The accompanying catalog can be used for constraining the physical properties of extragalactic objects, studying the AGN population, measuring the infrared colors of stellar objects, and studying the extragalactic infrared background light.</description><source format="bibcode">2018ApJS..234...38N</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/234/38</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/II/261">II/261 : GOODS initial results (Giavalisco+, 2004)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/93/145">J/ApJS/93/145 : Radio survey around north ecliptic pole (Kollgaard+, 1994)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/125/229">J/A+AS/125/229 : A standard stellar library (Lejeune+ 1997)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/130/65">J/A+AS/130/65 : A standard stellar library.
