_is_su(filename)[source]¶

Checks whether or not the given file is a Seismic Unix (SU) file.

Parameters:	filename (str) Seismic Unix file to be checked.
Return type:	bool
Returns:	`True` if a Seismic Unix file.

Note

This test is rather shaky because there is no reliable identifier in a Seismic Unix file.
