[Two chaps and two ladies point sternly at a box labeled "Bad Vectors".]
You see, when we find bad data, we like to make sure that nobody tries to do science with it. We collect up the corrupted vectors and put them in the Bad Vectors box. The chap on the far left, who is extra keen, seals up the box so that none of them can escape.
This is exactly how it works. Let no one tell you otherwise.
We also have special musical accompaniment, which includes such fine titles as "Calibration" by Carr & the Gang. We even won an award for our efforts, as shown below.

If we ever actually win an award for calibration, which is highly unlikely, I intend to insist that we recreate this photo. I think we all look quite dapper.
