Roseburg #6182A

The last portion of Line 1050 in the mag file was deleted as the data was not usable.

Resmag had to be calculated for Line 1070.  5000 feet were first added to the radaralt to 
provide the elevations needed.  IGRF75 was calculated using the elevations and the date 
of August 11, 1980.

Resmag was not changed in the rad file.
