Re: unexpected monochromator movement during velocity runs

John & Bo

Last year we went thru a period  where wavelength slipped during a run -
it occurred regularly - I was running the old dos version at the time.  It
was not unusal to see wavelength change occur between the 1st & 2nd scan
as well, but that did not persist thru the run.  This was clearly a new
problem.  - our solution was to change out the wavelength drive & the
problem went away.
