Spitzer Observations of the North Ecliptic Pole


الملخص بالإنكليزية

We present a photometric catalog for Spitzer Space Telescope warm mission observations of the North Ecliptic Pole (NEP; centered at $rm R.A.=18^h00^m00^s$, $rm Decl.=66^d33^m38^s.552$). The observations are conducted with IRAC in 3.6 $mu$m and 4.5 $mu$m bands over an area of 7.04 deg$^2$ 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 $mu$m 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 utilized in constraining the physical properties of extra-galactic objects, studying the AGN population, measuring the infrared colors of stellar objects, and studying the extra-galactic infrared background light.
