Notes. Numbers in parentheses are 1σ errors on the last
significant digit. Upper limits are evaluated at 3σ confidence level.
The uncertainties of the timing parameters have been scaled by a factor
to take into account a reduced χ2 of the best-fitting
model larger than 1. The orbital solution obtained modelling the Doppler shifts on the
pulse period is given in the leftmost column, while the best timing solution evaluated
from the phase evolution of the first and second harmonic are given in the central and
in the rightmost column, respectively. The reference epoch for these timing solutions
is MJD 55 483.186.
