Kozai::Illumination::PassIllumination
What the illumination of one pass looks like.
All three interval lists are in UTC and in order, and any of them can be
empty. They are lists rather than single spans because a pass need not
contain exactly one of anything: a satellite in a high orbit can be above
the horizon for hours and cross the shadow more than once, which is the
same reason Passes.narrow does not assume a single hump.

How the pass reads.
NOTE: a pass can fail both tests at once — a daylight pass with the satellite eclipsed as well. The station's own sky is named first, because it is the condition the observer can check by looking up.
Sun–satellite–observer angle at culmination, degrees.
Small means the satellite is nearly back-lit from the observer's point of view and looks its brightest; near 180 it is a thin crescent. This is reported rather than turned into a magnitude, because a magnitude needs the satellite's own brightness and size, and an element set carries neither.
