The convergence of the peculiar gravitational acceleration of the Local Group deduced from galaxy distribution and its alignment with the microwave background dipole are studied in the framework of linear theory and conditional probability. The acceleration generated in a volume of finite depth for general density fluctuations power spectrum is predicted. This is applied to the cold-dark-matter (CDM) and isocurvature baryon (PIB) family of models. The results are compared with IRAS and optical flux and redshift dipoles. The CDM predictions are in good agreement with the observations, while the PIB models show a wide range of behavior depending on the choice of parameters, Omega(b), h, and n. It is concluded that the alignment and convergence provide a useful discriminator between competing theories.
