the final remnant compact object. This is calculated using the disk mass
fitting formula from [#DiskMass]_ (Equation 4).
For preliminary estimates based on the matched-filter pipeline results, the
source properties are calculated using a supervised learning technique;
mass-dependent rates are the same as those used for the classification. For
parameter estimation, updated properties are calculated from posterior samples.
The way that these probabilities are calculated for preliminary alerts differs
for different search pipelines:
- For GstLAL, the probabilities consider the uncertainty in the
matched-filter estimates of the template parameters. The probabilities are
calculated using supervised machine learning on a feature space consisting of
the masses, spins, and :term:`SNR` of the best-matching template, described
in [#MLEMBright]_.
- For all other pipelines, the source property probabilities are reported as
exactly 0 or exactly 1 depending on whether the corresponding condition is
satisfied by the best-matching template. **In this case, these probabilities
do not capture uncertainty in the matched-filter estimates of the template
parameters, and should be interpreted with caution.**
