ARG00007ys, corejet, overlap.

Here's ARG00007ys, which appears to be an #overlap of two separate emissions, a #core-jet centre, and what appears to be a #compact, or maybe a #doublelobe, with no visible optical or ir host to the south.
The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
thread.The #corejet is centred on SDSS J141318.87+574531.5, a red galaxy, with a z_ph=0.610 ± 0.0508. It has an NVSS reference in NED, and an ALLWISE reference, ALLWISE J141318.86+574531.7. This ARG image is also listed in page 6 of the How to describe the radio morphology? thread.
With reference to the ARG comments left, and whether this is an #SDRAGN candidate, it has a fracDev_g, _r, of 0, and 0.131, and an expAB_g of 0.465 and expAB_r of 0.095, respectively. For c, the inverse concentration index, it has a figure of 0.675 for the g band and 0.393 for the r band. On the above parameters, it could possibly be a #disk galaxy, but the galaxy is very faint, and the radio emission appears to be only a #core-jet.
To the south is a lobe, which in the First cutout below, could be a #compact or maybe a #doublelobe. There doesn't appear to be any photometric objects or ALLWISE references related to this emission in SDSS or Aladin, and no visible optical or ir hosts. Interestingly, looking at the First cutout, I wonder which lobe is overlapping which?
Comments, suggestions, welcome.
