Boundaries between the Constellations

[Philosophaie]

The below sites formulate the Boundaries between the Constellations.

These sites leave inconsistancies or open gaps between the Constellations where there is no definition.

I was wondering if there is a more comprehensive listing on the Web or in a book I could buy on these Constellation Borders.

[Chronos]

Constellations are arbitrarily defined by ancient astronomical observations. I fail to see any issue.

Nancy Roman published a paper on figuring out which constellation any celestial position is in: see here.
