Units and field expansion

The keyword "utransport" indicates that the input has the following units

 angles in degrees except for $\Delta x'$ and $\Deltay'$ for the kicks

lengths in meters
energy in GeV
momentum in GeV/c
electromotive force in kiloVolts
frequency in Hz
field expansion is \(\displaystyle{B(x,0) = B\rho\ \Sigma_{n}\ K_{n}x^{n}}\)
positive $K_{1}$ is horizontally focussing
Also, the "utransport" keyword has implications for the field expansion coefficients.

The keyword ustandard indicates that the input has the following units


 angles in radians 

lengths in meters
energy in GeV
momentum in GeV/c
electromotive force in MegaVolts
frequency in MegaHertz
field expansion is $B(x,0) = B\rho \ \Sigma_{n}\ K_{n}{x^{n}\over{n!}}$
positive $K_{1}$ is horizontally focussing
