The LORRI sensor has a resolution of θ = 5µrad or 1 arcsec per pixel. We can do a simple geometric approach to see which distance x corresponds to a change in the apparent position of a nearby star (say d = 8 ly) of one pixel. This is simply $\sin \theta \cdot d = x = 2.5~\rm AU$. That would be the position precision, if the position of at least 2 nearby ...

Several sources (close to the end) show a table with a rough breakdown of the fuel use. The total amount of fuel of 77 kg was used both for trajectory change and attitude control. The Δv = 242 m/s number does not include the fuel used for the latter. There are 29.3 kg of fuel reserved for attitude control, leaving 47.5 kg for propulsion. Making the same ...
