Path: SpacecraftEstimation/StellarCatalog
% Load the Hipparcos catalog and create the near matrix
The catalog is limited by the specified minimum visual magnitude. A magnitude
of 5 gives about 1500 stars and a magnitude of 6.1 gives about 5000 stars.
Accounts for the stellar motion if a Julian date is entered.
