Remarks about protein structure precision. erratum
The following are corrections to the paper by Cruickshank [Acta Cryst. (1999). D55, 583-601]. On p. 589 section sign4.2 line 13, Zi# should read Zi; also in line 13, Zi should read Zi#. In line 18, Zi#, sigma(r) should read Zi#sigma(r). In the caption for Fig. 7, sigmadiff(2) should be sigmadiff(l). Equation (30) should read as follows, Sigma(r, Bavg) = 3(1/2) (Ni/p)1/2C-1/3 Rdmin (30) and equation (49) should read as follows, Sigmai2 = [( summation operator3 wDelta2)/(nobs - nparams)](a-1)ii (49). On the first line of p. 599, (47) should read (49).
