Williams Project 6042B & 6043

Totmag was unusable so it was calculated from the resmag.  No lines were deliberately dropped from the 
data set.  A large number of lines are missing in the middle.  They must have been removed when 
the data was originally worked up.

There are about 8-10 more flight lines in the radiometric file with residual magnetics than there
are in the magnetic file.  No effort was made to bring these lines into the magnetic file.
