Erratum: “Structure and Colors of Diffuse Emission in the Spitzer Galactic First Look Survey” (ApJS, 154, 281 [2004])

We have discovered an error in the scaling of our IRAC 8 m and MIPS 70 m data, which affected the caption for Figure 1 and the vertical axis scales for Figure 2. The original units in the images displayed in Figure 1 were MJy sr 1 for 8 m and Jy arcsec 2 for MIPS 24 and 70 m. We incorrectly multiplied our IRAC data by 0.0425 (the conversion from Jy arcsec 2 to MJy sr ), but neglected to multiply our MIPS 70 m data by that factor. (MIPS 24 m data were scaled correctly.) Thus, contrary to the caption of Figure 1, the gray levels for panels (a) and (b) actually range from 6.7 to 7.8 MJy sr , and the gray levels for panels (e) and ( f ) actually range from 0.85 to 20.8MJy sr . The power spectra in Figure 2 should have been normalized such that the integral over the spectrum equals the mean square image surface brightness. In the original paper, however, the IRAC power spectrumwas incorrectly multiplied by (0.0425), whereas theMIPS 70 m spectrum should have been multiplied by this factor but was not. We correct this in a revised version of Figure 2 included here. We thank Rick Arendt for calling our attention to this error.
