Notes. For each parameter, the Tempo2 one-sigma error on the last quoted digit(s) is reported in parenthesis. The parameters listed (except for the non measured parallax and orbital frequency derivatives) are the same as in Table 3. For two pulsars the ELL1 binary model (Lange et al. 2001) was used to fit orbits with low eccentricities (e); the reported values for e and the longitude of periastron ω have been derived from the EPS1 and EPS2 Laplace parameters given by the model, the limits are 95% upper limits. Pulsars whose names are in bold have been jointly timed in radio and gamma-rays. The reported spin period derivative (and derived parameters) have been corrected for the Shklovskii effect whenever a significant total proper motion μ was measured.
