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
- sgremovenoise() - works for specified sector; rewrites all DC banks removing single hits; calls function RemoveNoise() from SGUTIL
- sglib() - find segments for one sector; three options can be specified: noise removing only, segment finding only, noise removing and then segment finding; calls functions RemoveNoise(), SegmentSearch128() and SegmentSearch192() from SGUTIL
