Sgutil

SGLIB/SGUTIL package contains Dave Haddle's noise reduction software with segment finding extensions. It resides in $CODA/src/codatt/sgutil.c and is called from $CLON/src/cmon/prlib/sglib.c.

SGLIB contains following functions:

• sginit() - must be called once at initialization stage; creates differencial shift table and fills lookup tables

• sgtrigger() - works for specified sector; return 0 if sector does not have required track information, otherwise returns the number of superlayers with segments; calls function RemoveNoise() from SGUTIL
