When I run r.proj grass presents information about the source and target
maps; e.g.,

Input:
Cols: 11118 (11118)
Rows: 15536 (15536)
North: 1515424.500000 (1515424.500000)
South: 1468816.500000 (1468816.500000)
West: 610354.500000 (610354.500000)
East: 643708.500000 (643708.500000)
EW-res: 3.000000
NS-res: 3.000000

Output:
Cols: 10172 (647333)
Rows: 14209 (477579)
North: 249034.059746 (291528.074025)
South: 234825.054971 (-186051.086454)
West: 2286071.280048 (2167423.204862)
East: 2296243.286494 (2814756.615068)
EW-res: 1.000001
NS-res: 1.000000

I assume the first numbers are the actual values. What do the parenthetical
values represent?

Regards,

Rich
