    Hi Gary:

    Welcome to the world of celnav, and welcome to the NavList.

    Those are magnitude (i.e. "brightness") values for the planets. Larger
    numbers = fainter objects, while smaller numbers = brighter (with Venus and
    Jupiter literally being "off the scale" at -3.9 and -2.1). You should find
    similar entries for the "Selected Stars" on the yellow bookmark page.
