Thanks Andy,
I wonder how compact the emission line source is compared to the region shown in the radio image. (unfortunately the spectrum was not very well focused at H alpha so the extent is not clear in my spectrum)

EDIT this image and spectra from HST suggests the main emission region region extends around 1 arcsec or so across
