Track substracted wrong close orbit for other observer points then the start

[tpersson]

If onepass is NOT used the closed orbit is subtracted before writing to the file. The problem is that it is always the closed orbit at the start of the sequence that is subtracted independent of the observer point.

I actually wonder why we at all subtract the closed orbit in tracking. It makes a lot of sense to have the option to start the particle around a closed orbit but why removing it by default? Is this something we can change ?
