Pulsar Profiles and the q-Gaussian and q-BWF Line Shapes

The EPN Database of Pulsar Profiles contains data provided by several generous researchers. Data are proposed by means of a web plotting tool. However, the pulsar profiles can be also obtained from the database in plain text format and therefore they can be easily used to test fitting procedures. Literature reports pulsar profile fits made by means of Gaussian line shapes. Here we propose the use of the q-Gaussian functions, which are generalizing the Gaussian functions. Since the observed profiles are also asymmetric, we propose the use for fitting of the q-BWF functions too. These functions are generalizing the Breit-Wigner-Fano line shapes, with the Breit-Wigner factor substituted by the q-exponential function. The q-exponential was proposed by Constantino Tsallis for his statistics. Some preliminary fitting examples are here shown, of pulsar profiles from EPN Database.
