Program TracePlot, version 1.1; seismic trace plotting program for the Macintosh

Program TracePlot, Version 1.1, is a Macintosh software application to access a SEG-Y format seismic data file and display the seismic traces on the CRT screen of a Macintosh microcomputer. Both color and monochrome monitors are supported. Display modes are Wiggle-trace, Variable Area, or Wiggle plus Variable Area. Horizontal and vertical resolution is dependant upon the size of the monitor that is attached to the computer. The user controls the following parameters: 1) number of traces to be displayed on the screen at any one time, 2) the time window displayed, 3) the seismic trace in the file at which to begin plotting and trace increment to display thereafter, 4) plot direction 5) timing-line annotation increment, and 6) type of gain to apply (either constant gain factor, or trace-by-trace normalization). A pull-down menu provides interactive help during program execution. A utility program is also included which provides the function of copying a portion of a SEG-Y format data file to another file.
