(Bottom) TIR (a) and 12 μm (b) LFs for galaxies in the central region of the rich cluster A2199 (i.e., R < r _{200, A2199} ≈ 40′). Squares are the LFs based on the galaxies brighter than the SDSS limit. Circles include all the galaxies fainter than the limit. Open symbols are the raw LFs, and filled symbols are those after the corrections for photometric and spectroscopic incompleteness. The associated error bars indicate Poisson uncertainties. Vertical dashed lines indicate the luminosity limits at the redshift of A2199 corresponding to 3σ flux limits (3.6 mJy and 0.6 mJy for 22 μm and 12 μm, respectively). (Top) Number of galaxies used for the construction of the LFs in each bin for TIR (c) and 12 μm (d). Circles in the left panels are not shown because there are no 22 μm detections for galaxies fainter than the SDSS limit.
