Are Skynet Radio Measurements Consistent with XTEJ1118+480 Being a Black Hole with a Jet?

Question:

So, this question is regarding the Daisy scan data for XTEJ1118+480( A stellar mass black hole system) taken by Green Bank Radio Telescope. The link for the data is here : http://www.gb.nrao.edu/20m/idlinks/43812.htm I am particularly curious about how there are 2 pear-shaped lobes in the bottom right image ( XX1 reciever) . I am not sure as to what they signify but I have a guess .
Since XTEJ118 is a binary stellar mass black hole system consisting of a black hole a companion star. , these pear shaped lobes could jets of emission from the blackhole as seen in other Black hole systems like Cygnus X-1 .

It will be great to hear your opinion on the same considering your expertise in Radio Astronomy.

Answer:

Your interpretation of these radio measurements would be consistent with the overall structure of this object. As noted by Kanbach and collaborators in 2001, XTEJ1118+480 appears to contain a black hole with a relatively slow magnetically-controlled outflow.
