L_BS_PR2 is the separation between the center of BS chamber and the center of PR2 chamber.
The following table shows the the Folding parameters with three different cases of L_BS_PR2.
Case 1 is the default plan. Case 2 adds 2m to the BS-PR2 separation, and Case 3 adds 3m.

Location of PR2 tank

Is it possible to put the PR2 and SR2 vacuum chambers further away from the BS chamber ? The minimum separation is 2.7m (center-to-center). However, in order to improve the workability around the BS chamber, we want increase the separation.
