Base-Line Value Stability of Geomagnetic Variation ( II )
Yanagihara, K.
Abstract
Base-line values of KZ-type Z-variometer are analysed. Of the method described in Part Ⅰ of this report (Yanagihara, 1975) some modifications are required for some Z-variometers which show complicated characteristics, though there is no need of modification for good Z-variometers under normal condition. Method of analysis is studied for typical cases of abnormal condition. Practical application of the analysis for daily base-line value determination is discussed.
