Table 3.

Distances and Travel Times to Various Star Systems. (For each system, the left column lists the travel time $\tau$ (24) experienced by the travelers in units of days (d) and the right column lists the travel time t (25) experienced by those in the galactic (rest) frame in units of years (y).)
