Quantification of the parameter estimation error from Rotating Core Collapse supernovae
An analytical model for core-bounce gravitational waveforms estimates the rotation parameter β with 94% average fitting factor to numerical templates and derives error bounds below 0.1 via matched filtering and Cramér-Rao comparison in O4 noise at 5-50 kpc distances.
