tsp is *not* in the TS package, and it is documented in help(tsp) to give
`the start time in time units, the end time and the frequency.''
Who `expected'' the values you gave, and why `should'' they be
expected to
differ from the documentation?

What in your opinion is the correct number of df, and what is your
reference? Have you checked the references given on the help page?
