Hard aspects in ecliptic longitude and prime vertical longitude both work. In the later case, my limited experience is the the latter type may be effective even if not foreground. I would appreciate hearing thoughts on this, but my main interest is the validity of aspects on the horizon (measured in azimuth). It appears these have some validity. Would this also apply to planets which are not close to the meridian or the vertex anti-vertex axis?

Watching over the de ades, since so-called Local Space charts had their day, I've seen a few cases that briefly made me think azimuth aspects worked; but, overall, they haven't been persuasive.

The only thing I can vouch for (and technically only in ingresses) are tight (say, 3 degree), conjunctions, oppositions, and squares by planets within tight (again, say 3 degree) conjunction with the meridian or PV in azimuth. These may be a firm of co-angularity but I doubt that since the proximity to the PV does not itself have an "angular" feel. Also, any planet exactly on PV squares a planet exactly on the meridian(measured along the horizon) or horizon (measured along the meridian).
