Image Details
Caption: Figure 2.
An illustration of the GALFIT fitting in six broadband filters for three galaxies of different morphological types. Images are 3﹩\mathop{.}\limits^{^{\prime\prime} }﹩0 on a side. Results for each galaxy are shown in three rows. Top row: a color composite followed by images of the galaxy in each individual filter. Middle row: model color composite followed by the GALFIT model in each filter. Bottom row: residual color composite followed by the residuals obtained by subtracting the best-fit model in each filter. The galaxy ID in the CEERS catalog and its photometric redshift are listed in the color composite image panel. The best-fitting Sérsic index n and effective semimajor axis re for each filter are listed in the middle row for each model. CEERS-56498 (top) is an elliptical galaxy, well fit by an n ∼ 4 profile in all bands. CEERS-80909 (middle) is a face-on disk whose spiral arms are noticeable in the residuals. CEERS-74656 is an edge-on disk with a dust lane that is noticeable in the transition from blue to red wavelengths, and results in uneven residuals.
