distinguish leak and crossing surface
seemingly done
elseif syntax error
floor typo
done without uncertainty
clear code
physics error, rm peak at interface
debug, absorption probability
debug, peak before interface is physics incorrect
there might be no code update but it is clear the peak comes from increasing sigt
batch run to get uncertainty
debug, subtract column from matrix
normalize rate by space
question 3“
shift counter position to bin center
peak explanation
rearrange
question 4
add assumption to question 4
rearrange question indexes
