Low Orbit Velocities List?

I've never seen one. I've needed the info before but always estimated and cobbled through.

It's niche enough that I doubt you'll do better than what you have here, which seems a perfect resource for your needs. You can get some of this info from the dV maps like this one here but they only list Kerbin, Sun and Jool. It's the number between the elliptical orbit and the circular orbit. You could create your own map or ask the maintainers if they'd consider adding it.

Note you can get this info from the game without too much trouble by creating a maneuver node to circularize the orbit and note how much the dV is, however that won't help you much in the VAB.

Also, note that the info display for each planet in-game gives you the escape velocity.  Just divide that by the square root of 2 and you'll have the orbital velocity at the surface.

It'll be off a little, yes, because your target orbit's a bit higher than the surface.  But not all that much, compared with the planet's radius-- it'll come reasonably close.

Alas eyeball is the only tool available.
