(HP-97) Field Procedures & Data Reduction Methods (sensitivity surveys)

[SlideRule]

Extract(s) from Field Procedures and Data Reduction Methods for Total Field Resistivity Surveys, USGS, Report 78-424.

IV. DATA REDUCTION AND PROGRAM DESCRIPTIONS
Two programs for HP 97-67 programmable calculators are given in the Appendix. The first program (Program I) is for the calculation of the average magnitude and direction of the total potential difference from three horizontal components, whereas the second program (Program II) is for the computation of the simple-total-field apparent resistivity and other parameters of interest.

VI. APPENDIX
A summary of user instructions and program listings for Programs I and II are given on the following pages. Note that the given key codes are for the HP 97. The key entries of SPC (space) may either be deleted or replaced by PAUSE for HP 67 users.

Complete & Thorough!

BEST!
