Bob's response pretty much covers it.
The only thing I might add is about other tabular methods that allow plotting from a DR position (what Bob calls an EP) rather than an AP. The only mainstream one (besides the variants of H.O. 211) that is included in Celestial Tools is H.O. 214, but only in the delta d, delta t, delta L mode.
