# 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.
