                         (SGRs) and Anomalous X-ray Pulsars (AXPs) could be described as 
                         rotation-powered neutron stars (NSs). The analysis was carried out 
                         by computing the structure properties of NSs, and then we focus on 
                         giving estimates for the surface magnetic field using both 
                         realistic structure parameters of NSs and a general relativistic 
                         model of a rotating magnetic dipole. We show that the use of 
                         realistic parameters of rotating neutron stars obtained from 
                         numerical integration of the self-consistent axisymmetric general 
                         relativistic equations of equilibrium leads to values of the 
                         magnetic field and radiation efficiency of SGRs/AXPs very 
                         different from estimates based on fiducial parameters. This 
                         analysis leads to a precise prediction of the range of NS masses, 
                         obtained here by making use of selected up-to-date nuclear 
                         equations of state (EOS). We show that 40% (nine) of the entire 
                         observed population of SGRs and AXPs can be described as canonical 
                         pulsars driven by the rotational energy of neutron stars, for 
                         which we give their possible range of masses. We also show that if 
                         the blackbody component in soft X-rays is due to the surface 
                         temperature of NSs, then 50% of the sources could be explained as 
                         ordinary rotation-powered pulsars. Besides, amongst these sources 
                         we find the four SGRs/AXPs with observed radio emission and six 
                         that are possibly associated with supernova remnants (including 
                         Swift J1834.9-0846 as the first magnetar to show a surrounding 
                         wind nebula), suggesting as well a natural explanation as ordinary 
                         pulsars.",
