The SHOW DATA command displays a list of values and properties. Take 26-tone equal temperament for example. 0.020229 steps, 0.7831 cents Pyth. It shows how good the basic intervals major third, perfect fifth and harmonic seventh are approximated in an equal temperament. Misfit numbers are an invention of Fokker and are sums of squared errors in cents.
Relative errors are a percentage of the average deviation in terms of step size.
The average error is a quarter step, because the error varies between zero and half a step. Combined error factor , from Mandelbaum, is the sum of the squared errors of the first basic three divided by the size of half a step. This makes it a kind of normalised version of the misfit number M3. The second combined error factor is given if the highest consistently represented harmonic is 9 or higher. The number of possible Pythagorean generators is the value of Euler's totient function for the given division.
