Are their sources providing tentative coordinates for where orbiters like Venera, Pioneer Venus, Venus Express, or Magellan may have entered the atmosphere much like those for the Pioneer Venus Multiprobe bus at 37.9°S 290.9°E? (Magellan maybe impossible due to it being a farside deorbit)

I have been asking this question for years. Basically there should be answers to the questions in every case except Venera, whose orbiters might still be in orbit or will have decayed at an unknown date. For the other orbiters the orbit is known very well. The entry will be at periapsis and the latitude of periapsis will be known. The orientation of the orbit in space plus the time of the entry will give the longitude if somebody can put it together. I don't have the information to do it, but out there in spacecraft operations land the information must exist. But I have never seen it all put together. Please, orbit wizards, figure it out for us!
Now, with positional uncertainties and atmospheric uncertainties, the locations might only be accurate to a degree or so. But it would be really nice to be able to say 'Magellan burned up over Beta Regio' or 'Venus Express entered over Fortuna Tessera' and of course, to plot them on a map!
