There appears to be some link rot here.

CO To recap:-

CO (For the 7 known superluminals in 1983,) the structures did NOT in
CO general appear to be oriented close to the line-of-sight;

CO Mackay, Thompson et al suggested in 1993 that the (outer) jet of
CO quasar 3C273 was nearly PERPENDICULAR, rather than nearly
CO parallel, to the line-of-sight. Superluminal motion of up to
CO ~9.6c has been observed along the (inner) jet;

I can find no paper in ADS with the authors "Mackay" and "Thompson."
Perhaps you could post a reference?

There's a paper in Nature 9 September 1993, vol 365 no 6442
"Internal structure and polarisation of the optical jet of the quasar
3C273" RC Thomson CD MacKay and AE Wright, but I don't have access
online.
