SSB and SSB_cur #260

Closed mle2718 closed 1 year ago

mle2718 commented 1 year ago

I noticed the outputs SSB and SSB_cur are saved. Can someone help me figure out the difference between these two?

Looks like the SSB is calculated like this using the Jan-1 abundance from the previous year https://github.com/lkerr/groundfish-MSE/blob/72ef93b48c7603bda40f0f78dc2127bc3d1019ca/functions/popdy/get_J1Updates.R#L21

And the SSB_cur is using the abundance for the current year, calculated like this https://github.com/lkerr/groundfish-MSE/blob/72ef93b48c7603bda40f0f78dc2127bc3d1019ca/functions/popdy/get_J1Updates.R#L82
