I don't know of any paper published on this. Still, Pioneer-11 was sending such data back over the time period, so I imagine that an interested reseacher could take the issue up. I think it sad that Pioneer 11 wasn't sent on to Uranus and Neptune.
Yes, it definitely returned data then. A look at plots produced here:http://lewes.gsfc.nasa.gov/cgi-bin/cohoweb...?spacecraft=p11
shows that it was a little patchy, especially plasma density, velocity, etc., but there's probably enough magnetic field data to directly compare with Voyager 2. As this was nearer solar minimum than maximum, most of the solar wind structure would have been corotating with the Sun, i.e. there wouldn't have been many CMEs producing localised disturbances. This would definitely make the comparison simplier.
