Sanwal et al. [Astrophys. J. 574 (2002) L61] supposed that it is very difficult to interpret the absorption features in terms of cyclotron lines. However, we would like to address here that the possibility of the absorption being cyclotron resonance cannot be ruled out. We propose that the isolate neutron star, 1E 1207.4-5209 in the centre of supeova remnant PKS 1209-51/52, has a debris disc and is in a propeller phase, with an accretion rate ~ 6 × 10-11M⊙/year. In this scenario, 1E 1207.4-5209 could also be a bare strange star.
