SMC-Last Mosaic Images

Abstract: We present mosaic images of the Small Magellanic Cloud (SMC) observed with the Spitzer IRAC 3.6 $\mu$m and 4.5 $\mu$m bands over two epochs, 2017 August 25 to 2017 September 13, and 2017 November 24 to 2018 February 12. The survey region comprises $\sim$30 square degrees covering the SMC and the Bridge to the Large Magellanic Cloud. The region is covered by 52 $\sim$1$.!!^\circ$1$\times$1$.!!^\circ$1 tiles, with each tile including images in each band for both separate and combined epochs. The mosaics are made in individual tangent projections in J2000 coordinates. The angular pixel size is 0$.!!^{\prime\prime}$6 with a resolution (FWHM) of $\sim$2$.!!^{\prime\prime}$0. We describe processing to correct or mitigate residual artifacts and remove background discontinuities. The mosaic images are publicly available at the Infrared Science Archive (IRSA).
