Our study is distinctive due to (1) the much deeper ($\\sim200$ hour) wide-area Spitzer/IRAC imaging at $3.6\\mu$m and $4.5\\mu$m from the GOODS Re-ionization Era wide Area Treasury from Spitzer (GREATS) program and (2) consideration of $z\\sim6-10$ sources over a $3\\times$ larger area than previous HST+Spitzer studies.
