SED of the transient during the second epoch of SDWFS. We fit a blackbody SED that includes the dust emissivity ( Q ∝ λ ⁻¹) to the four IRAC bands (filled circles) and find a best-fitting temperature of T = 1357 ± 57 K (dotted line). We also show a template SED for the host galaxy modeled as an irregular (dashed line; Assef et al. 2010) and the combination of the modified blackbody and irregular galaxy SEDs (thick solid line). Overplotted are the V, R, and IRAC filter transmission curves, "normalized" to 5 × 10 ⁴¹ erg s ⁻¹. The MDM (QUEST) limit is derived for an observation taken 90 (~40) days prior to the second epoch of SDWFS. The CRTS limit corresponds to the stack of three epochs (12 × 30 s images) taken between SDWFS epochs 3 and 4. The open squares mark the NDWFS B _W, R, and I-band measurements for the host galaxy (from left to right).
