Casper Projects 6001A and 6093E

Only the resmag was complete but it looks like it needs some leveling. The
totmag was recalculated from the resmag and, therefore, also needs leveling.
The totmag and resmag may be different from that in Project 6001, Wind River
Basin.
 
The original report states no corrections were applied to the magnetics 
but, when merged with the 1978 lines, some corrections may have been 
applied.    

About three lines on the south and fill-in lines in the northeast were 
flown in 1978.  It also appears the tie lines were flown in 1978 and maybe
parts of some of the lines.  The remainder was flown in 1974.  

GJBX 158(79) gives a description as to how the two surveys were merged.
