SUBROUTINE FFEVT0(DEVT0,ZNOM,VXYZ)
**********************************************************************
* *
* Calculate the event T0 correction (no e-bunch timing correction *
* at the moment) *
* *
* OUTPUT: *
* DEVT0 is the event T0 correction *
* ZNOM is the nominal z vertex *
* VXYZ is the event vertex position *

*
* Per-track values can go in H1WORK; note that LTRUE and LFIRST must
* be set at least per event.
*
* This is about 36k words long; the remaining common blocks are
* about 3.6k in total. Some of this could be in /H1WORK/, but the
* blocks would have to be reorganised.

**********************************************************************
* Get the nominal z-vertex if available
* The nominal interaction point is deemed to be at x=y=0
CALL VZERO(VXYZ,2)
* If the CJC has found a vertex, use it
C INVERT = NLINK('CTKV',0)
* Lose dependence on CTREC to aid reprocessing
* If the error is bigger than 50 cm its not worth doing
& CALL UCOPY(IW(INDCR(INVERT,1,JPRIM)),VXYZ,3)
* Event T0 correction
