Hi Fran,
Rick can correct me if I'm wrong, but I would think that you could
use this option near the top of the forecast file
5 # Forecast: -1=none; 0=simple_1yr; 1=F(SPR); 2=F(MSY) 3=F(Btgt) or F0.1; 4=Ave F (uses first-last relF yrs); 5=input annual F scalar
(followed by input of the annual F scalar).
Then use these option further down in the file to turn on allocation
among fleets:
2 # fleet relative F: 1=use first-last alloc year; 2=read seas, fleet, alloc list below
(followed by a table with the relative F for each fleet in each
season, ending with a -9999 row).
I'm sorry I don't have time to try to work up an example right now to
try it out, but you can keep checking the echoinput.sso file to see if
the model is interpreting your inputs correctly.
It may take some iteration to get the annual F scalar correct, but
iterating one value is better than iterating over the three F values
for the fleet-specific F in each year.
