DBSCAN Algorithm for Space Debris Removal: Refining Target Selection and Neighborhood Definition

To refine the sentence:

The initial selection of a group of target debris locations required a set speed increment, which served as the 'sample set'. The 'neighborhood' was described as the fuel consumption threshold required by the space vehicle from one debris to another, while 'Minpts' was used to describe the potential debris removal threshold within the allowable range of fuel consumption around a certain debris.
