Which l2gen routine computes the total backscatter coefficient (b) from IOP values?

Hi.  When using l2gen to calculate QAA  IOPs  'b_nnn_qaa' is among the L2 products available (along with 'bb_nnn_qaa' and 'bbp_nnn_qaa').  I've looked through the source codes, but haven't figured out where the 'b' (which I assume is the total scattering coefficient) comes from.  I'd like to see how it is done in SeaDAS so I can add the same method to an R implementation of QAA I'm working on.  Thanks.

I found this in ocssw-src/src/l2gen/get_qaa.c:310

b = bb * 53.56857 + 0.00765;

Thank you, Don.  I missed that when I went though the source code because I looked right past the 'case CAT_b_qaa' block.  I appreciate your help.   Barry
