Refraction studies in the North American Levelling Datum NAVD 88
Abstract Despite the noisy character of the data in the new North American levelling net (Zilkoski et al. 1989) it is quite easy to see the refraction corrections mirrored in the polygon closing errors if one takes only those polygons with sufficiently high refraction corrections. The following table illustrates this point. In the table the first column denotes the limit of the accumulated refraction corrections (found from temperature measurements) along a polygon, that is only polygons where the refraction correction exceeds this limit participate in the analysis. The second column is the estimate of the correlation coefficient between refraction corrections and the closing errors of the polygons while the third column is the significance level in the conventional student-test of whetherr is different from zero.
