ARG00017lt - diffuse emisson in NVSS around spiral?

by Dolorous_Edd
the FR1 double in right center of the picture belong to SDSS J080822.33+390059.1
however there is more emission in visible in NVSS to the S
around SDSS J080823.31+385929.2 - 1237655108895637875
TGSS ( something is visible at noise level in the area of NVSS emission )

Here's a First TGSS overlay of this ARG field centred on SDSS J080823.31+385929.2, which is SSW of the ARG co-ordinates listed left.
The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
thread. First in red, TGSS white.TGSS emission is very extended and hard to determine host or hosts.

Chris, can you also do NVSS, please?

Here's the NVSS TGSS contour overlay

maybe try lower noise value? just by eyeballing there is seems to be more emission at the noise level

Here's another image, but this is right at the edge of the margins.
Tnsignoise = 0.0001 # TGSS noise floor, in sigmas
Tsf = np.sqrt(1.4) # TGSS contour scale factor
Tsmooth = 13.0 # sigma for gaussian smoothing (TGSS contours)The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk

And here's the NVSS with lower noise value.
