Various solutions are possible.
A reoptimisation of the geometry or an optimisation of the tracking parameters do not seem feasible given the timescale for the productions. This may not be adequate for very fast tracks but further reduction would be too costly in terms of performance. This is NOT the case in our code and it should be changed. It is also desirable that the coil be integrated in the cryostats in order to facilitate the maintenance of the relevant code. S. O'Neale has introduced a SLUG warning concerning the correct use of datacards.
