I'm writing unit tests for the Oregon Coordinate Reference System. The ArcGIS conversion does not match sample data provided by Oregon. Is it me or is it ArcGIS? I compared with an open source library based on proj4 and its conversion gives the expected results.

 

Baker Zone

Input:

44 49 57.80936, 117 48 54.56244

converted to:

44.832724822222225, -117.81515623333333

 

Expected:

Easting: 41437.60083
Northing: 36980.20833

 

Got:

Easting: 41438.67098

Northing: 36979.55245

 

I tried Authority IDs of both 6784 and 6786. I used 4326 for the input coordinates.
