The streaming model describes the mapping between real and redshift space for 2-point clustering statistics. In this talk, we discuss the implications of using ordered and unordered pairs on the streaming model. We highlight that, while one recovers the classic equation for ordered pairs, modifications to the streaming model are required for unordered pairs. In the latter part of the talk, we introduce a new fitting function known as the generalised hyperbolic distribution for the pairwise velocity PDF and showcase the fidelity of the streaming model using it. Our results are useful for extending studies of anisotropic galaxy clustering towards smaller scales in order to test theories of gravity and interacting dark-energy models.
