Input Cards

FE_METHOD $\parbox{0.75\linewidth}{ {\textrm{\it{{\underline{porbits}}}}}}$
$\parbox{\MY}{Method selector for this step. currently there is only one method.}$

FE_DEGREE $\parbox{0.75\linewidth}{ {\textrm{\it{{\underline{5}}}}}}$
$\parbox{\MY}{degree of 2d polynomial.}$

FE_NPOINTS $\parbox{0.75\linewidth}{ {\textrm{\it{{\underline{501}}}}}}$
$\parbox{\MY}{Number of points to compute reference phase for least squares estimation.}$

FE_IN_POS $\parbox{0.75\linewidth}{ {\textrm{\it{filename}}}}$
$\parbox{\MY}{ascii file with positions (master coord. system) in it ... ...id excessive fluctuations at the edge if a higher degree polynomial is used. }$

FE_OUT_FILE $\parbox{0.75\linewidth}{ {\textrm{\it{filename}}}}$
$\parbox{\MY}{Card will be added in future for optional output of reference phase.}$

One can use an awk like to make a grid:

 awk 'BEGIN{for (i=100;i<25200;i=i+500)   \
             {for (j=750;j<5400;j=j+200)  \
               {printf "%i %i \n",i,j}}   \
	    exit}' > positions.in

and a card in the input file:

 FE_IN_POS   positions.in

This step used to be named ''FlatEarth''. This explains the prepended FE_'s, instead of some abbreviation for reference phase.
