<p>
<a class="link" href="GwyCalData.html" title="GwyCalData"><span class="type">GwyCalData</span></a> is an object representing general calibration data of a SPM
system. Any point in the volume that can be reached by SPM scanner can be
characterized by two vectors: error and uncertainty. Errors can be used for
further data correction, uncertainties for propagation and determination of
final uncertainty of results of direct measurements or statistical
functions. Using different strategies a different number of these local
calibration data can be obtained, starting from single uncertainty applied
for whole system up to complex determination of local SPM errors and
uncertainties.
