Appendix B: LTT error determination
The error on the LTT correction is estimated using the standard deviation
constructed with all the pixel pairs used to compute
.
The offset correction is based on
Eq. (4). For a pixel pair
((
)
and (
)) that have seen the same sky at different time,
the offset at time ti is given by:
![\begin{displaymath}\begin{array}{ll}
\Phi(\alpha, \delta, t_i, t_j) = &
F(\alph...
...{\Delta(t_j)}{F(\alpha, \delta, t_j)} \right]\cdot
\end{array}\end{displaymath}](/articles/aas/full/2000/18/ds8759/img79.gif) |

We have evaluated the statistical error on the offset correction

where n is the number of pixel pairs.
