Summary

The text files that contain data and models in a form for plotting have the filename extensions .ROT and .ROZ. These files were compressed into zip files by each type, for example, SLV2007_rot.zip and SLV2007.roz.zip. The .ROT file contains the following information: 1) The sounding name; 2) Tab delimited column headings for the data that follow; 3) Tab delimited time and apparent resistivity data consisting of 6, 9, or 12 columns corresponding to 1, 2, or 3 transmitter repetition frequencies, respectively. Typically, the data are given in order of decreasing repetition frequency corresponding to later time ranges. The contents of the columns are specified in table 2–9 (Fitterman, 2016). When a sounding has fewer than 3 base frequencies [...]
