Reference orbit display

This operation computes the orbit defined by the initial coordinates x x' y y' $l \ \delta$, and provides either a printout or a printer-plot display.

Input format 


REFErence ........(maximum 80 characters) 


nprint sizex sizey 

$x_{0},x'_{0},y_{0},y'_{0},l_{0}, \delta{0}$ 


npos ${\rm pos}_{i}$ for i from 1 to npos.

Parameter definitions

nprint controls display

1 a printout is provided

2 a printer-plot is provided

11,12 $\parbox{10cm}{ same as for 1 and 2 , the orbit is a 4-dimensional closed orbit in the space defined by the variables x,x',y,y'}$

21,22 $\parbox{10cm}{ same as for 1 and 2 , the orbit is a six-dimensional closed orbit in the space defined by the variables x,x',y,y',l,$\delta$.}$

sizex,sizey $\parbox{10cm}{ They define the boundaries between which the coodinates x and y are plotted. They are always needed in the input stream}$
. $x_{0},\dots \delta$ $\parbox{10cm}{ six coordinates of the input particle traced to determine the orbit}$
. npos $\parbox{10cm}{ number of positions selected for interval computation maximum 4}$
. ${\rm pos}_{i}$ $\parbox{10cm}{ the rms values are computed individually in all the intervals defined by the values 0,${\rm pos}_{i}$ and the end of lattice}$

Examples

The example comes from dem06.
