The X-ray power-density spectrum of the accreting millisecond pulsar XTEJ 1807-294 contains several triplets of simultaneously observed quasi-periodic oscillations (QPOs): a lower and a upper kHz QPOs and a low-frequency QPO. This fact allows us to assess the mass and the specific angular momentum of the central neutron star. We also apply an error propagation formula to obtain interval estimates of the parameters of the star. The calculations are repeated with several different models for the kHz QPOs. The degree of consistency of the bounds obtained with the different triplets may provide information for the viability of the used models.
