Sažetak
The dependance of the measured apparent synodic solar rotation rate on the height of the chosen tracer is studied. A significant error occurs if the rotation rate is determined by tracing the apparent position of an object above the photosperic level projected on the solar disc. The center-to-limb variation of this error can be used to determine simultaneously the height of the object and the true synodic rotatition rate. The apparent (projected) heliographic coordinates are presented as a function of the height of the traced object and the coordinates of its 'footpoint'. The relations obtained provide an explicit expression for the apparent rotation rate as a function of the observed heligraphic coordinates of the tracer, enabling an analytic least-squares fit expression to determine simultaneously the real synodic rotation rate and the height of the tracer.
