Notes
The GMOS-S image of this NLRG/FRII shows a clearly disturbed morphology, including features such as a broad fan towards the east (μ_V = 23.4 mag arcsec^−2), a bright shell to NW and a fainter shell towards the west (μ_V = 23.3 and 24.6 mag arc- sec^−2, respectively: Ramos Almeida et al. 2011a). The unsharp-masked image also shows several bright knots of emission closer to the galaxy centre. Emission-line contamination of the features is not a serious issue here because strong emission lines do not fall in the r′-band filter employed in our observations. Inskip et al. (2010) also report the detection of the NW shell (or arc-like feature) in their K-band images. It is possible that the host galaxy is interacting with a smaller, extended companion object to the east.
The optical spectrum shows a rich, high ionization emission-line spectrum. The optical emission lines are clearly extended in this object. Although the optical continuum spectrum does not require a young stellar population (any UV excess can be explained in terms of AGN-related continuum components), a low EW PAH feature is detected in the Spitzer IRS spectrum (Dicken et al. 2011).

Spectral energy distribution. The blue solid line is fitted to the data from 109 to 1010 Hz. Extrapolating this line from the radio to the infrared SED tests whether non-thermal synchrotron emission from the lobes can contaminate the Spitzer mid-infrared flux. In this case the lobes emission lies out of the Spitzer beam so cannot contaminate the Spitzer data. The, flat spectrum, non-thermal radio core emission is also not likely to contaminate the Spitzer infrared flux data for this object.
