theta: ambient point index (matching the metricSpace passed to compute) to its circle coordinate in [0, 1) -- only for points in the connected component of K_r containing the chosen class (see the class doc); a point outside that component has no entry at all, not a sentinel value. birth/death are the chosen bar's own full-filtration endpoints (death = Double.PositiveInfinity for an essential bar); r and prime echo the parameters compute was called with.
