code		description
DUAL		Dual negative exponential: PMR= P1t0*exp(-k1*t) + (1-P1t0)*exp(-k2*t) where PMR is proportion of mass remaining, P1to is the proportion of part 1 at time zero, t is time in years, and k1 and k2 are the decomposition ra
LAG		Modified Chapman-Richards to include lag term: PMR= 1-(1-exp(-k*t])^Lag where PRM is proportion of mass remaining, t is time in years, and k and Lag are the model parameters
SINGLE		Single negative exponential: PMR=Int*exp(-k*t) where PMR is proportion of mass remaining, t is time in years, and k is the model parameter
