Observation metrics for periodic events

A Python package to compute and visualize observation metrics for periodic events.

In Astronomy, nighshift is useful to answer the following questions:

• How much of an orbit with period $P$ has been observed given certain observation times? (tutorial)
• What period $P$ matches with this list of events? (tutorial)
• How a certain target must be observed to cover all orbits with periods lower than $P$ days?
