The main interest for the miscellaneous calibrations stems from the information they provide on short and long term temperature and structural changes of the satellite. In particular the on-board clock drift showed how the spacecraft reacted on variations in solar radiation, as caused by the ellipticity of the Earth orbit and as due to solar eclipses.
The gyroscope drifts also showed temperature dependencies, as well as dependencies on the rotation phase of the satellite (gyroscope harmonics). The gyroscope transformations, showing the sensitivities to rates on the payload axes, shows some peculiarities, such as a noticeable change in the transformations when a fourth, redundant, gyroscope was activated. The gyroscope noise correlations is a record of performance of the gyroscopes in general.
