Ovunc,
you can reference the x and y variables with a replace.
Let's say you want the x value from the fifth result -- so take the second element from the fifth result (which is the list of x and y rules):
x /. c1[[5, 2]]
You can use this to restructure your results into a matrix:
lookupTable = Map[{#[[1]], x /. #[[2]], y /. #[[2]]} &, c1];
and look at it as a grid:
Grid[lookupTable , Frame -> All]

or export / use it.
