Remarks
10 Jul. 2003: The planet parameters are very uncertain. They are derived from Hubble data by measurements of the white dwarf companion characteristics (Sigurdsson et al, 2003)1999: The 1.35 MSun pulsar is in a binary system (period = 191.4428 d.) with a 0.6 MSun white dwarf companion (Thorsett et al. 1999); this explains the uncertainties in the fitting of the planet parameters.
