==Outcrop changes==
In light of borehole interpretation, it was necessary to make some small changes to the outcrop of some units, this is illustrated in Figure 2 (the original DiGMAP extract) and Figure 3 (the geological units used in model calculation).

==Marlstone rock formation==
In the southwest of the model, around Middleton Cheney (SP44SE, SP54SW) there is a dense grid of bores for ironstone, into the Marlstone Rock Formation. Base of MRB was taken at the base of the lowest significant ironstone bed (>0.15 m) (also agreed with Mark Barron who modelled Area 3).
