ERRATUM: ‘‘INFRARED OBSERVATIONS OF THE HELIX PLANETARY NEBULA’’ (ApJ, 652, 426 [2006]) Joseph L. Hora, William B. Latter, Howard A. Smith, and Massimo Marengo Due to an error at the Press, Figures 1 and 2 were printed in the incorrect orientation. Both of these figures should be rotated by 180 . The correctly oriented figures are reprinted here. The Press sincerely regrets this error.
Fig. 1.—Three-color image of the Helix, showing the regions that were imaged in all IRAC bands. The 3.6, 4.5, and 8 m IRAC bands are mapped to blue, green, and red, respectively. The orientation of the mosaic is in array coordinates, and the vertical axis is 59N6 east of north (see Fig. 3). The image is approximately 24A2 ; 26A2 in size.

Fig. 2.— Same as in Fig. 1, except showing the 12 0 ; 11 0 region around the central star. This shows the structure of the knots inside the main nebular ring.
