"The solutions we are going to present ... have been built from VSOP87"

Its not a description on how VSOP was programmed. The article is about taking data from VSOP and trying to manipulate it.

sort of, but not really. read the abstract and section 3. "solutions" means "the positions of the planets at a given time."

vsop87 is a model of the solar system using

*only*the elliptic parameters of each planetary orbit (semi-major axis, eccentricity, inclination, etc.). but just knowing elliptic parameters isn't useful. we want to know physical coordinates of the planets at a given time. that's what vsop87a, vsop87b, etc, are for. they're just outputting the positions of the planets in different coordinate/reference systems.

look at this table:

vsop87 describes each orbit in terms of the shape of the orbit (elliptic parameters). vsop87a-e describe the positions of the planets in terms of different coordinate and reference systems (eg rectangular vs spherical).

all of these inputs and outputs are in terms of real, physical quantities: the shape of the orbit, the distance from the sun or barycenter, the mass of the object, etc. i cannot find anything in these documents that describes the kind of pattern-counting that you say astronomy relies upon.
