95NB2CG Statistical Weight, ^LRSW, analysis (1985ZiZY,1992Ra09) of the six
95NB3CG values 0.34 {I13} (1969Br29), 0.6 {I2} (1969Fo01), 0.4 {I1}
95NB4CG (1972Er08), 0.67 {I7} (H. H. Hansen et al., 1973, as quoted in
95NB5CG 1975De17), 0.54 {I3} (1975De17), and 0.43 {I2} (1976Ho04). This
95NB6CG analysis increases the uncertainty of the value of 1976Ho04 from 0.02
95NB7CG to 0.026 to reduce its relative weight from 63% to 50%. The resulting
95NB8CG internal uncertainty is 0.019, the reduced-|h{+2} is 3.2, the
95NB9CG external uncertainty is 0.03, and the LRSW analysis expands the final
95NBaCG uncertainty to 0.06 to include the most precise value of 0.43. Other
95NBbCG values are 4 (1966Ts01), <0.4 (1967Br21), and 4.5 {I19} (1968BoZX).
95NBcCG Since the six values used are discrepant, one can also deal with this
95NBdCG discrepancy by use of the ^RAJEVAL method (1992Ra08) which increases
95NBeCG three of the uncertainties and gives 0.438 {I19} or by the Normalized
95NBfCG Residual method (1992Ja06) which increases two of the uncertainties
95NBgCG and gives 0.447 {I31}.
