1 Sample Definition And Size
The study measured the effective zenith noise temperature of a single 20‑foot horn‑reflector antenna at 4080 Mc/s (7.35 cm wavelength) located at Crawford Hill Laboratory, Holmdel, New Jersey, over the period July 1964 to April 1965. The sample consists of repeated measurements from this one instrument over that time span.
2 Study Type
Observational experimental measurement study using radio astronomy instrumentation.
3 Conflicts Of Interest
No conflicts of interest are declared in the available abstract or metadata.
4 Results Summary
The measured antenna temperature was approximately 3.5 K higher than expected. This excess was found to be isotropic, unpolarized, and showed no seasonal variation over the observation period. No statistical values such as p‑values or confidence intervals are provided in the abstract.
