Archive records support a tenfold date scale for 44 first-season TOI-4562 velocities

We tested whether public CHIRON observation records explain the dates of 84 published TOI-4562 radial velocities. The same date, velocity, and error triples appear in the arXiv PDF, arXiv HTML, and final journal PDF. The printed dates span 40.99 days in 2017. The paper states observations from December 2020 to January 2022. The proposed map is t_candidate = 2450000 + 10(t_printed - 2457000). Independent records support this scale for all 44 first-season rows. For 35 rows, candidate dates agree within 1.4 seconds with the EMMNWB exposure-meter field after a BJD TDB calculation. Five associated EMMNWB means fall outside their 1,200-second exposures. All corresponding EMMNWOB means lie inside the exposures. One other row has invalid meter dates and matches a shutter-start time. Eight rows match archive start-date records. The other 40 dates remain unchecked. The proposed map therefore identifies observations but does not certify all exposure times. We also tested two fixed Newtonian orbit examples with outer periods of 1,507 and 4,500 days. Under the proposed dates and two fitted white-noise terms, twice their log likelihood difference is -0.269. A control using 36 physical header times gives -0.268. This comparison does not refit the orbits or establish an error in the original velocity corrections. The package preserves source documents, exact headers, provenance, code, figures, and reproduction checks.
