This report details corrections to a 1974 study on Earth's rotation using radio interferometry. It clarifies time scale headings and adds a symbol for accuracy in geodetic measurements.

Area of Science:

Geophysics
Astronomy
Radio Interferometry

Background:

A previous study by Shapiro et al. (1974) measured Earth's rotation using transcontinental baselines.
Radio interferometry was a key technique for precise geodetic measurements.

Purpose of the Study:

To provide errata for the 1974 report.
To ensure accurate interpretation of time-scale data and measurement precision.

Main Methods:

Review of Table 1 in the original publication.
Identification of specific textual and symbolic errors in the data presentation.

Main Results:

Correction of the heading for columns 5 and 6 of Table 1 to "Atomic time-universal time (A.1-UT.1)".
Inclusion of a double dagger symbol after the second entry in column 1 to denote specific measurement conditions.

Conclusions:

The corrections ensure clarity and precision in the presentation of Earth rotation data.
Accurate scientific reporting is crucial for the validity of geodetic and astronomical measurements.
