 5  All of the elliptic theta functions are functions of two parameters: 
 6  the argument ''z'' and a second argument. For these routines the 
 7  second argument is the nome ''q'', {{{q < 1}}} . Some references 
 8  use the the lattice parameter ''tau'', with the imaginary part of 
 9  ''tau'' strictly positive. 
 10  
 11  The nome and lattice parameter are related by {{{q = exp(%i*%pi*tau)}}}.
