Query: Data Selection Criteria for Spectroscopic Measurements of Neutron Star
  Radii with X-ray Bursts   Data selection and the determination of systematic uncertainties in the
spectroscopic measurements of neutron star radii from thermonuclear X-ray
bursts have been the subject of numerous recent studies. In one approach, the
uncertainties and outliers were determined by a data-driven Bayesian mixture
model, whereas in a second approach, data selection was performed by requiring
that the observations follow theoretical expectations. We show here that, due
to inherent limitations in the data, the theoretically expected trends are not
discernible in the majority of X-ray bursts even if they are present.
Therefore, the proposed theoretical selection criteria are not practical with
the current data for distinguishing clean data sets from outliers. Furthermore,
when the data limitations are not taken into account, the theoretically
motivated approach selects a small subset of bursts with properties that are in
fact inconsistent with the underlying assumptions of the method. We conclude
that the data-driven selection methods do not suffer from the limitations of
this theoretically motivated one.
