ARG0003848 overedge, doublelobe, SDRAGN candidate?

Here's ARG0003848, an #overedge, #doublelobe.
The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
thread.The host appears to be SDSS J120204.64+081240.8, (in the centre of the above contour overlay) a #disk or #spiral galaxy, with a z_ph=0.146 ± 0.0356, and lobe size of ~2' or ~200 kpc, (as per the classification comments).
There is also an ALLWISE reference for this galaxy, ALLWISE J120204.59+081240.3, but there are also ALLWISE references for SDSS J120206.29+081226.1 and SDSS J120207.28+081218.1 which are ESE of SDSS J120204.64+081240.8 respectively.
Here's a zoomed in image of SDSS J120204.64+081240.8. A possible SDRAGN candidate?

A possible SDRAGN candidate?
I certainly think so! 😃
fracDeV_g, _r, and _i are 0.26, 0, and 0.03, respectively. That means it's quite likely a disk galaxy (or a disk-dominated one), not an elliptical. c, the inverse concentration ratio, for the g band is 0.435, and for the r band, 0.41. So, ditto. It's not quite 'out-of-round' enough to be unambiguously an Eos (or highly inclined disk); expAB_g, for example is 0.37 (the threshold is ~0.30).
So, SDSS J120204.64+081240.8 is almost certainly a disk-dominated galaxy ... but is it the host?
