Next: Imaging by an Optimizing Method . ... A big advantage of this numerical integrator is its stability: the error in the semi-major axis and the eccentricity depends only on the step size and does not grow with an increasing number of time steps. ... As the integration time increases, the numerical results become more contaminated by various errors. ... A new symplectic integrator produces no secular truncation errors in the actions of a Hamiltonian system. ...

... Appropriate values of DIT the integration time (DIT secs) for each individual integration, are lmited by various considerations. N.B. Ndit individual Integration s each of DIT secs are coadded to form a single Exposure of time Ndit*DIT]. The recommended minimum DIT is one sec (the minimum possible exposure time) or the value at which the noise becomes sky (rather than detector) limited. ... The recommended maximum DIT is such as to keep the detector wells less than half full. ... 40 sec . ...
