Caption: Figure 3.

WISE 4.6 μm band (W2) contains CO 4.7 μm and CO₂ 4.3 μm emission lines. C/2009 P1 Garradd's 4.6 μm band excess is not consistent with reflected or thermal contributions of coma or nucleus, but is consistent with CO₂ and CO emission. The flux from the 3.4 μm (left red triangle), 4.6 μm (right red triangle), 12 μm (left orange diamond) and 22 μm (right orange diamond) channels are shown. Also the reflected light model (dotted line) thermal model (solid line) and combined signal (dashed line) are over-plotted.
