extracted flux of the fake source in the catalog was brighter at 3.6 and 4.5[$\mu$m]{} but fainter at 5.8 and 8.0[$\mu$m]{}. The process was repeated a 100 times to measure the average systematic and statistical error using the corresponding point spread function at each of the four IRAC wavelengths. We revise the aperture corrected magnitudes for JD2 to 22.24, 22.00, 21.63 and 21.51 AB mag at 3.6, 4.5, 5.8 and 8.0 [$\mu$m]{} respectively. There is, however, a correction to be applied to these magnitudes.

There are three faint galaxies within 1$\arcsec$ of JD2. Two of these are rather faint and blue while the brightest of the three falls within the IRAC 3$\arcsec$ beam. These galaxies are detected at all wavelength between the $B$ and $H_{160}$ band. To estimate the contribution of these sources to the photometry within the IRAC beam, we fit @BC03 templates to the multiband photometry of these sources, leaving redshift as a free parameter. We use the best fit SEDs to estimate the redshift and corresponding flux densities at the IRAC wavelengths. We find the brightest of these three sources, located at 3:32:38.76,-27:48:28.91 (J2000), to be at redshift 3.4 with magnitudes of 25.95, 25.83, 25.82 and 25.80
