Sasmirala Individual Information for 3C 353
Description
3C 353 is a FR II radio source identified with the giant elliptical galaxy LEDA 60102 [madrid_hubble_2006] at a redshift of z = 0.0304 (D ~ 138 Mpc) with a Sy 2 nucleus [veron-cetty_catalogue_2010]. It features supergalactic-scale biconical radio lobes in the east-west directions with both jets being visible (PA~ 85∘; e.g., [morganti_radio_1993, swain_internal_1998]). 3C 353 was not detected with IRAS and appears as a weak compact source in the WISE images. In addition, an, to our knowledge, unpublished Spitzer/IRS LR mapping-mode spectrum is available but suffers from a very low S/N. No spectral features can be discerned clearly apart from a shallow emission peak around ~ 18 μm in νFν-space (and possibly silicate emission). [van_der_wolk_dust_2010] performed VISIR imaging in the SIC filter and claimed a non-detection with a flux upper limit of 4 mJy. However, in our reanalysis of the image, we weakly detect a compact emission source at the expected beam positions. No conclusion about the nuclear morphology can be drawn from this low S/N data, however.

Images
Optical image (DSS, red filter). Displayed are the central 4 arcmin with North being up and East to the left. The colour scaling is linear with white corresponding to the median background (BG) and black to the 0.01% pixels with the highest intensity.
Subarcsecond-resolution MIR images sorted by increasing filter central wavelength. Displayed are the inner 4 arcsec with North being up and East to the left. The colour scaling is logarithmic with white corresponding to median BG and black to the 75% of the highest intensity of all images in units of sig_bg. The inset image (where present; either bottom or top right) shows the central arcsecond of the PSF from the calibrator star, scaled to match the science target. The labels in the bottom left state instrument and filter names (C: COMICS, M: Michelle, T: T-ReCS, V: VISIR).
SEDs
MIR SED. The description of the symbols in all the SED plots (where present) is the following: Grey crosses and solid lines mark the Spitzer/IRAC, MIPS and IRS data. The colour coding of the other symbols is as follows: green for COMICS, magenta for Michelle, blue for T-ReCS and red for VISIR data. Darker-coloured solid lines mark spectra of the corresponding instrument. The black filled circles mark the nuclear 12 and 18 micron continuum emission estimate from the data (where present). The ticks on the top axis mark positions of common MIR emission lines, while the light grey horizontal bars mark wavelength ranges affected by the silicate 10 and 18 micron features.
