unusually low luminosity X-ray source.

In a recent paper, @Dunlop question the optical limits in the $B$, $V$, $i$ and $z$ passbands adopted by @Mobasher and demonstrate that the $\chi^{2}$ values in the redshift fits are skewed in the @Mobasher analysis by adopting optical flux limits which are too stringent. By refitting the source with revised optical limits, they conclude the source to be at $z\sim2.2$ rather than at $z\sim6.5$. We also note that JD2 has been visited in work by @Yan:04 and @Chen prior to the @Mobasher analysis, and had been classified as a $z\sim3$ ERO.

In this paper, we present new 16[$\mu$m]{} and 22$\mu$m photometry of this source from [[*Spitzer*]{}]{}  Infrared Spectrograph (IRS) peak-up imaging of the GOODS fields [@Teplitz:07]. We fit the photometry at these two wavelengths and the published 24[$\mu$m]{} data with a variety of dust spectral energy distributions and demonstrate that the mid-infrared photometry is most consistent with a redshift of $z\sim1.7$ for JD2. We assess the accuracy of the optical/near-infrared photometry and refit the data with this redshift constraint to determine physical properties of the galaxy. We conclude that it is a luminous infrared galaxy with L$_{\rm IR}\sim10^{11.7}$ L$_{\sun}$ and not a $z>6$ galaxy
