L = km surveyed on effort. n = number of primary sightings used in the analysis. E[s] = estimated mean group size (%CV). esw = effective strip half width in m (%CV). D = density (animals per km−2) (%CV). N = estimated abundance (%CV). 95% CI (N). CV = coefficient of variation and CI = confidence interval.
