The .mg File

The main output file, entitled filename.mg, contains four columns. The first is the MCD Group number assigned by plvdkey.exe; the second and third are the original MCD and precinct codes (preserving the county prefix); and the fourth column is an indicator, by precinct, of how many MCD Groups were created in that county. So, when output in the .mg file, which is sorted by MCD Group, no two rows in the same county have different numbers in the fourth column. These columns are delimited by tabs.

Using Indiana once again as an example, the .mg file looks like this:

001     001085  0010119 16
001     001085  0010101 16
002     001040  0010110 16
002     001040  0010102 16
