Repair an inconsistent X-ray spectral-timing analysis
An X-ray timing group is replaying a two-band quality-control observation with the historical scientific-software source supplied in this task. The observation loads successfully and the Fourier calculation completes, but the returned frequency-dependent products do not satisfy the statistical behavior described by the supplied method material.
Run the offline reproduction, inspect the complete observation and historical source, and repair the implementation so the reconstructed analysis agrees with the required observation semantics. The repair must generalize to other valid simultaneous light-curve inputs supported by the project.
Do not hard-code this observation, a filename-specific result, or report fields. Do not modify the supplied observation, public reproduction, or generated reports.
