Table 9 
Output statistics for q gross for the run with the Bayesian update and with the uncertainty factor applied. Posterior means (mean), 
standard deviations ( SD), and coefficients of variation (CV ) are given. The last three columns show the 2.5 th , 50 th , and 97.5 th per- 
centiles. WCV=west coast of Vancouver Island; QCS = Queen Charlotte Sound; HS=Hecate Strait. WCHG =west coast of Haida 
Gwaii.

Table 10 
Posterior correlation matrix for the natural logarithm of the q gross values for the seven surveys off British Columbia, during 
bocaccio ( Sebastes paucispinis ) were captured. The index number in the first column and first row indicates the survey for which 
the correlations apply. See Table 9 for a key to the survey indices.
