&FIELD: MULTIPOLE-MOMENTS
Number of the wire for which the multipole decomposition must be done.
[No default.]
Order of the highest multipole moment.
Dipole moments are computed for ORDER=1 and higher, quadrupole moments
for ORDER=2 and higher etc.
[Default: 4.]
Distance from the wire at which the decomposition is to be carried
out. The parameter r is expressed as a number of wire radii.
[Default: 1, i.e. at the wire surface.]
The 'small number' used by the fitting routine to calculate the
covariance matrix.
[Default: 10\<SUP\>-4\</SUP\>.]
The maximum number of iterations that the fitting routine may do.
[Default: 20.]
Requests a plot of the potential around the wire and of each of
the terms in which it has been decomposed.
The following representations are used:
- FUNCTION-1:
potential on the surface of the wire;
- FUNCTION-2:
multipole fit to the potential around the wire;
- FUNCTION-3:
the various multipole terms - the terms are easy tell apart
by counting the number of maxima and minima, with the dipole term
having just one of each, the quadrupole two etc.
[This plot is by default not made.]
Requests information about the fitting process be printed.
[This information is by default not printed.]
