... Instead, we only get timing information when data are dumped to the ground from the onboard computer from which we may infer when things happened. ... A UDL is always dumped from the spacecraft prior to the start of a science exposure, effectively flagging the start of the observation. ... For RAPID mode observations, the data are dumped as soon as they are taken. ... For ACCUM mode observations, a second UDL is dumped at the end of the exposure and prior to reading out any science data. ...

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. ...

Using XPA remotely ================== XPA starts by default using network communication with access control. ... Copy and append id_dsa.pub to $HOME/.ssh/authorized_keys on the system you are connecting to. ... If you are connecting from an observer's computer to a telescope computer that is not on a local area network, you may also need to change the firewall settings to enable SSH. ... The ssh command forward the port 5901 on your local computer to the same port on the telescope computer. ...

This groups includes about 200 communication satellites ("comsats") scattered in synchronous orbits above the Earth's equator. ... 6 Earth radii (42,000 km or 26,000 miles), these satellite make one orbit per day, and therefore as the Earth turns, they always stay above the same ground station. ... Still another application is the 24-satellite network of the "Global Positioning System" (GPS), in circular orbits at distances of about 4.1 Earth radii (26,000 km or 16,000 miles). ...

Next: Standard orientation Up: Preprocessing Previous: Bias correction . In a similar manner, long dark exposures of the same exposure time can be averaged to produce the DARK frames. ... Use the command COMPUTE/IMAGE to multiply the images by the exposure time and to add back the value for FLAT_BKG . ... Often, BIAS and DARK contain no large - scale structure. ... The commands AVERAGE/IMAGE and AVERAGE/WEIGHT offer number of options to compare the images and filter particle hits. ...

... First of all, I should say that you cannot guarantee user-mode processes to have exact control of timing because of the multi-tasking nature of Linux. ... However, for most applications using I/O ports, this does not really matter. To minimise this, you may want to nice your process to a high-priority value (see the nice(2) manual page) or use real-time scheduling (see below). ... Linux 2.x kernels have soft real time support; see the manual page for sched_setscheduler(2) for details. ...
