2 months ago It seems that I have understood the meaning. The sum of all the sensitivities of the s.f.s equals one, e.g. 100%. So, we can treat the sensitivity of each s.f. as the contribution to the total sensitivities, and the contribution of each s.f. can be regarded as proportion. The threhold of 0.5% means the contribution to the total sensitivities less than 0.5% will be discarded. The sensitivity here just likes the degree of rate control (DRC) in the microkinetic simulation, where the sum of DRCs of all elementary reactions is also 1.
The question Dear n2p2 developers, I am reading the doc of n2p2 these days. When I tried to understand the command of "nnp-prune sensitivity", the doc tell me that the "nnp-prune sensitivity 0.5 max" means the threshold is set to 0.5% where 100% is equal to the total sum of all sensitivities. I wonder what does the "total sum of all sensitivities" mean? Does the 0.5 mean the program will delete the s.f.s whose sensitivities rank in the last 0.5%?
