six pairs of satellites are identified through the indices of bound star particles. As output of the AHF code, we use in our satellite analysis only the list of bound dark matter and star particles. There are cases when the halo finder does not detect one of the objects at a particular epoch either due to the pericenter shock or temporary interference with other large subhalos. Such events will appear as unavoidable interruption of the flow of data points on the analysis plots. As soon as the object is identified again by the AHF code, the flow of data points in the analysis plots resumes.\
The center of the satellite is defined as being the position of the stellar density peak of the respective object. From this point a 3D half light/mass radius can be defined as the radius of the sphere centered on the previously mentioned density peak which includes and excludes half of the mass amount of bound stellar particles. All the values of the half light radius associated with each object at the available evaluation epochs are presented in figure \[fig:figure7\]. The next step in the preparation of the satellite data for analysis is the alignment of
