Trace Picking Utilities

For lack of a better location to discuss this is the subject, we will now list``trace picking'' utilities. The X-Windows wiggle trace, image, and contour plotting programs all have the attribute that by placing the cursor on the point to be picked and typing the letter `s' the coordinates of the point are saved in memory. When the letter `q' is typed, the values are saved in a user-specified file ``mpicks.''

There are two additional programs which are dedicated to picking issues. These are

• XPICKER - X wiggle-trace plot of f(x1,x2) via Bitmap with PICKing
• SUXPICKER - X-windows WIGgle plot PICKER of an SU data set
• SUPICKAMP - pick amplitudes within user defined and resampled window

with ``xpicker'' being the non-SU data version which ``suxpicker'' calls. The xpicker/suxpicker programs are interactive tools for picking. The program ``supickamp'' is a simple automated picking program, which seeks the largest amplituded within a user-specified window.

See demos in $CWPROOT/src/demos/Picking for more information about ``supickamp.''
