The computed pointing error for a platform tilt track the measured errors pretty well. ...

... In order to compare the number of different evolutionary stages obtained and X-ray luminosity of the chosen X-ray sources with the observed galactic values we use the sum of C/O+O/C , where C and O are the calculated and observed values of a given binary type, respectively. If we make comparison for a number of different binary species (for example, we compare the number of CV, number of X-ray pulsars,   total X-ray luminosity of LMXB, etc.), we write this criterion in the form: . ...

In addition, the Chinese had two different ways of interpreting and observing celestial events. One way the Chinese used astronomy was known as lifa; it was a discipline that aimed to understand the regularities and the predictable events in the celestial system through careful, observations, measurements and records. ... back to Teachers' Newsletter Main Page ...

Observing Facilities . ... Observing with ESO Telescopes . ... However, if you want to process science data from different nights together you should limit the available calibrations to those from one night as the pipeline assumes that the calibration data were taken without mask movement in between. ...

... Energy . ... The free ions and electrons in a plasma behave the same way. Knowing the temperature of the high atmosphere of Earth, or that of the Sun, we can calculate energies expected of ions and electrons found there. However, ions and electrons actually observed in space are often much, much more energetic, and may move at a respectable fraction of the velocity of light (300,000 km/sec or 186,000 miles/sec). ... Typical energy of an electron in the polar aurora. 40,000 ev . ... 50,000 ev . ...

... VLBI Schedule . ... Two different antenna are used for observing at ASKAP - AK07 has an L-band feed permanently installed while AK32 has an X-band feed installed. ... There are 3 main processes run for ASKAP observing. askap_drv is the main telescope control. It itself consists of a terminal based control process and a GUI. askap_drv must be running. VLBI scheduling is run from a process called "vlbi_drv", while the actual recording is via a command line process called px14_record. ...

It is possible to piece together the processes that have shaped the observed characteristics of a galaxy by studying its stars in detail. The Large Magellanic Cloud (LMC) is an excellent candidate for this type of study because of its favourable viewing angle and ongoing star formation. I present the results of high-resolution VLT/FLAMES observations of ~80 red giant stars around star cluster NGC 1846, located in the disc of the LMC. ...

... The results are used in quasireal time by the observing process, but also as input by hardware quality control, by the dynamical scheduler, and by the Science Pipeline. Among processing operations are the calibration of the atmospheric absorption, of phase radiometric correction, of pointing scans, of phase and amplitude reference measurements, .. ... Using the last few measurements, we will determine a provisional amplitude calibration curve (to be also used by the Quick Look pipeline). ...

... Astronomical image processing applies a large variety of numerical methods to extract scientific results from observed data. The standard computational techniques used in this process are discussed with special emphasis on the problems and advantages associated with them when applied to astronomical data. ... In Section the transformation of raw observed data into intensity calibrated values is discussed while general image processing techniques are reviewed in Section . ... Basic Concepts . ...

OM fast mode data are fully processed by the XMM-SAS Pipeline: for each exposure of a given observation all necessary corrections are applied to the data files. Then a pseudo-image is built from the corrected event list and a source detection algorithm is used to find the source (or sources) present in the fast window. ...
