Fission rate from Twig

The way the fission rate is calculated is as follows: Figure 2C in http://emboj.embopress.org/content/27/2/433.long is used. This gives a cdf of the probability that fission occurs given that we were fused before. From this graph one can read off that the accumulated probability to fission is about 75% for t in the range (250,280). So

1 - exp(- lambda_fis * U(250,280)) = 0.75 > lambda_fis = - log(0.25) / U(250,280) per second per mitochondrion, so it's -log(0.25)*60/U(250,280) per minute per mitochondrion, which gives www.caladis.org/compute/?q=-log(0.25)%2F%24a*60&v=a%3Aunif%2C250%2C280&x=off&n=m&h=fd&a=rad&_=1430230586335 that lambda_fis is more or less uniformly distributed between 0.30 and 0.34 per minute per mitochondrion.
