Boston Project 6011B This is an excerpt from the larger data set but the Boston data still remains in the larger set. A lot of basic information was missing from the data. Channels had to be created for geology, diurnal, fid, day, time, and resmag. Resmag was calculated using a DIGRF. No regional field had been removed from the original data. Although the days were available for parts of the data set, the first day of September was chosen for the whole set. The Boston quad was excerpt for a study completed in 1980. There is very little correlation between the rad file and the mag file. The line numbers do not agree and correlating between lats and longs would be difficult.
