[daip] problems with vlant

[bob at physics.ucdavis.edu]

hi, i ran vlant by mistake on a file that shouldn't need it.
much to my surprise vlant came back with inappropriate changes
to baselines. below is the information. the changes it found occured about
8 months after the observations were taken.
