摘要: A procedure for the analysis of photometric and kinematical profiles elliptical galaxies based on a family spherical, pressure supported, self-consistent two-component models described in previous paper is developed as tool to study presence dark halos such systems. Several tests simulated objects are performed order show that this able recognize matter, when sufficiently accurate extended available; some these have been carried out flattened (E4 E6), establish how geometry can affect our conclusions
