My first guess is that maybe the slit height was not specified to be significantly larger than the slit width giving fringing effects in both dimensions. Is this the case?

Also you may want to recheck your units to be sure you are indeed in the far field where the Fraunhofer approximations are valid.
 

Thread 'Modeling a graph that shows age in relation to depth of an ice sample'

To solve this, I first used the units to work out that a= m* a/m, i.e. t=z/λ. This would allow you to determine the time duration within an interval section by section and then add this to the previous ones to obtain the age of the respective layer. However, this would require a constant thickness per year for each interval. However, since this is most likely not the case, my next consideration was that the age must be the integral of a 1/λ(z) function, which I cannot model.
