The second half of the column shows the differences in cents from the nominal values of these partials, where we have as relative frequencies 15, 30, 36, 45, 60, 75, 90, 120 for the hum through the double octave, and nx40 for I-(n+3). The list with OTHER give a selection of the most prominent frequencies found that could not be identified. It is not sure that all the given partials belong to the bells. Some may come from exterior sources or may come from the suspension of the bells. SLAG = the strike note based on a = 440 Hz, well-tempered temperament and indication of cents. The strike note is defined as being one octave below the nominal partial. DIAM = the diameter of the bell in cm from own measurement. GEWT = the weight of the bell in kg as found in the literature. GWST = an estimated of the weight of the bell from the diameter and the frequency of the nominal. This estimated is given by the empirical formula: W = (d / 22.2 cm)^4 * (f / 528 Hz) kg where d is the diameter of the bell and f the frequency of the nominal GWMN and GWMX give the minimal and maximal estimate of the weight of the bell. This is given by replacing in the previous formula 22.2 cm by 22.7 cm and 21.7 cm respectively. It is found that most bells have weights within these limits. The formula is only valid for bronze bells with standard profiles. EQGW = the weight in kg that a bell with the same profile but scaled to sound exactly a c1. 2300 kg is an average value for a bell with a normal profile. Heavier weights indicate a heavy profile, smaller weights indicate a light profile. FD = the product of the diameter in m and the frequency of the hum in Hz, as computed by Bert Augustus. Value in m/s. Like EQGW it is a measure for the profile of the bell.
