Rodriguez, B.D., Johnson M.R., Sampson J., Falvo, C.I.P., Enns, K.D., Bell, T.M. and Everette, A.L., 2018, Magnetotelluric Data from the San Andreas Fault, Parkfield CA, 1990: U.S. Geological Survey data release,


The original time series and cross power data were stored in Binary format on 3.5" disks until further conversion was needed. To convert the time series and cross power data to a format that can be used for modeling, the original binary files were converted to ASCII format using Basic 4.0 code and associated subroutines (see Magnetotelluric_Original-Code_Binary-to-Ascii.txt and Magnetotelluric_Original-Code_Binary-to-Ascii-Subroutines.txt attached to the binary data ScienceBase item). The DaR project used these converted ASCII format files to create the EDI format files included in this data release. The binary data are considered the original data for the magnetotelluric survey, therefore, they are provided with the data releaseas [...]

Historic magnetotelluric data still exists in binary format and cannot be used for modelling or analyses unless it is converted to a format compatible with modern systems. The original binary data and codes are included here so users can understand and utilize the process of transforming the raw data from its inaccessible form to more versatile ASCII files.
