- Abstract
The form of Equation (6) also simplifies correcting for known biases: the bias-corrected value of HT <math altimg="urn:x-wiley:08856087:media:hyp14483:hyp14483-math-0040" display="inline" xmlns="http://www.w3.org/1998/Math/MathML"><msub><mi>f</mi><mi mathvariant="normal">A</mi></msub></math> ht is simply the biased value, minus the differences HT <math altimg="urn:x-wiley:08856087:media:hyp14483:hyp14483-math-0041" display="inline" xmlns="http://www.w3.org/1998/Math/MathML"><mtext>BIAS</mtext><mfenced close=")" open="("><msub><mi> </mi><mi mathvariant="normal">M</mi></msub></mfenced><mo>-</mo><mtext>BIAS</mtext><mfenced close=")" open="("><msub><mi> </mi><mi>AB</mi></msub></mfenced></math> ht divided by HT <math altimg="urn:x-wiley:08856087:media:hyp14483:hyp14483-math-0042" display="inline" xmlns="http://www.w3.org/1998/Math/MathML"><msub><mi> </mi><mi mathvariant="normal">A</mi></msub><mo>-</mo><msub><mi> </mi><mi mathvariant="normal">B</mi></msub></math> ht .
