    Hi Flemming,

I've made a slewing correction test on run 5592 (pol A, 8 deg. I think).
The results are improved, I get a time res. of about 87 ps, 
(without, it gives ~ 105 ps).

Plost can be checked out here:

http://www.nbi.dk/~ouerdane/h1TofRes.gif (with all momenta, should be less 
                                          with small momentum bin) 

Now, since the time offsets are needed for a slewing correction, I would 
think we should make a slewing corr. for each time offset cal. revision 
but I'm not sure. If so, one has to use the calibtool and check time 
offset revisions from run 5361 or so (unless we want to use earlier runs).

Djam
