public class LongShortStoN
extends java.lang.Object

Adapted from reftrg.f from Tom Owens and reftrig.c from Passcal. c c routine to apply the reftek trigger algorithm c to a designated SAC file c LTA is initialized to STA after 2 STA time constants c Trigger detection begins after trgdly seconds c c compile with: f77 reftrg.f $SACDIR/lib/sac.a -f68881 c c Written by T.J. Owens, August 16, 1988 c
