        files for use with PmagPy plotting software

        SPEC: 1  specimen name is same as sample (if SPEC is 1, sample is all but last character)
    NOTES:
        Sample naming convention:
            [1] XXXXY: where XXXX is an arbitrary length site designation and Y
                is the single character sample designation.  e.g., TG001a is the
                first sample from site TG001.    [default]
            [2] XXXX-YY: YY sample from site XXXX (XXX, YY of arbitary length)
            [3] XXXX.YY: YY sample from site XXXX (XXX, YY of arbitary length)
            [4-Z] XXXXYYY:  YYY is sample designation with Z characters from site XXX
            [5] site name = sample name
            [6] site name entered in site_name column in the orient.txt format input file  -- NOT CURRENTLY SUPPORTED
            [7-Z] [XXX]YYY:  XXX is site designation with Z characters from samples  XXXYYY

       Orientation convention:

                i.e., dip is degrees from vertical down - the hade [default]
            [2] Lab arrow azimuth = azimuth-90; Lab arrow dip = -dip
                i.e., azimuth is strike and dip is hade
            [3] Lab arrow azimuth = azimuth; Lab arrow dip = dip-90
                e.g. dip is degrees from horizontal of drill direction
