Artefact or radio source?

• by sisifolibre

  First this seems to me a faint doublelobe, but don't have counterpart in NVSS then may be an artefact caused by SDSS J102523.29+372648.9 - 1237662226205180042 to the NE.
  In other hand in FISRT it has his brightest pixel at 1.25 mJy, that is under the NVSS sensitivity, and P(S) is 0.027

  Is an artefact or is a real lobe with host SDSS J102523.29+372648.9?.

  I'd say it's more likely an artifact than real: in the FIRST image it looks like a sidelobe, a sorta blurred, fainter version of the triple in the NE:

  

  The host for that radio source seems to be zsp 0.045 SDSS J102523.29+372648.9:

  

  Perhaps ivywong or 42jkb could give a professional opinion? Also, what's the P(S) for these two faint FIRST sources?
