Sasmirala Individual Information for ESO 416-2
Description
ESO 416-2 is a radio-loud spiral galaxy at a redshift of z = 0.0591 (D ~ 251 Mpc) hosting a Sy 1.9 nucleus [veron-cetty_catalogue_2010] that belongs to the nine-month BAT AGN sample. Our VISIR observations in three narrow N-band filters during one night in 2009 are the first MIR observations of ESO 416-2. A compact nucleus was weakly detected in all images. Due to the low S/N of the detection no extension analysis can be performed, and no conclusion about the properties of MIR SED can be drawn.

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.
