Blocks used in the flowcharts
Master/slave variable MS_init is input for each of the three procedures.
Variable used in multiple procedures
xx is a list of values stored in the first column of the map XY_map.
yy is a list of values stored in column in XY_map
yy_out is the particular value of yy to find row n. xx(n
