Detailed Description

FittedStars are objects whose position or flux is going to be fitted, and which come from the association of multiple MeasuredStars.

x/y Coordinates are in the Common Tangent Plane (degrees). MeasuredStars from different CcdImages that represent the same on-sky object all point to one FittedStar.
