Editing SU Data

Once the data are read in, and the headers are set properly, then there will often be manipulation and data editing issues to be dealt with.

It is often necessary to perform tasks of varying so that data may be

• windowed,
• sorted,
• truncated,
• tapered,
• zeroed,
• made uniform in number of samples,
• concatenated,

which are dataset editing issues.

This section, therefore will deal with the following programs

• SUWIND - window traces by key word
• SUSORT - sort on any segy header keywords
• SURAMP - Linearly taper the start and/or end of traces to zero.
• SUTAPER - Taper the edge traces of a data panel to zero.
• SUNULL - create null (all zeroes) traces
• SUZERO - zero-out data within a time window
• SUKILL - zero out traces
• SUMUTE - mute above (or below) a user-defined polygonal curve with the distance along the curve specified by key header word
• SUVLENGTH - Adjust variable length traces to common length
• SUVCAT - append one data set to another (trace by trace)

which provide a variety of trace editing utilities.
