<L> denotes average flagellar length in μm, with standard deviation listed. <Diam> is the average cell diameter in μm. r is the correlation coefficient between flagellar length and cell diameter. η2int and η2ext denote the uncorrelated and correlated components of variation, respectively. Noise measures η2 listed are the actual measurements multiplied by 100. n is the number of cells measured. 95% confidence intervals for noise measures are given in parentheses.
