    Ciao Yiannis,

    in fact the VAX time on VSMAC1 was wrong at that time.
    This is the right situation:

        run 90103 LED/TDC (not SMT) started: 10JAN96 at 10:45
         " 90104 FMT " " " " at 11:05
         " 90107 LASER low. " " " " at 11:40
         " 90108 LASER att. " " " " at 12:00

     There are ~ 15.5 hrs of difference between the LGB time and
     the real acquisition time.
     I found the same problems for the following week (17JAN96) and
     no problems starting from run 90113 (24JAN96).
     Unfortunately I didn't find any comments on the paper logbook.

     Note that the two previous weeks (03JAN96 and 27DEC95) the
     calibrations were performed using VSMACR while three weeks
     before (20DEC95) were performed using VSMAC1 w/o problems.

     I hope that my previous e-mail regarding the NOV95 gain setting
     has been useful for your work. Anyway I'm at your disposal for
     any other questions.

     A presto,

                               Nicola
