... The effect of the bug has been that timestamps indicating when data was taken (FITS-header keyword CRVAL5) may be off by one second. ... DETAILED DESCRIPTION -------------------- AFFECTED KEYWORD: The affected keyword is: CRVAL5 (time stamp indicating start time of subscan) Synchronisation errors between the 1PPS pulses and the NTP-controlled system clocks have frequently caused the timestamps indicating the start of each subscan (CRVAL5) to be off by one second. ... That problem has also been fixed...

... Problem 5. ... See figure 1 for the light curve of these narrow Nitrogen lines. ... Figure out the behaviour of each parcel of gas, and then add them all up to find the light curve. 5.4 (3pts) Using expression from problem 5.2, derive the expression for the time after SN explosion date, when the first light from the ionised ring reaches Earth. Using the expression from problem 5.2, derive the expression for the time after SN explosion date when the maximum brightness of the ring occurs. ...

XMM-Newton Science Analysis System . ... A different approach is done via the setting withctisrcpos =Y: all event energy corrections do not use the actual RAWY coordinate but the corresponding RAWY location of the source ( SRCPOS ) as determined by the task epframes (either automatically or via setting withsrccoords =Y). ... The task epchain may be used with the setting ccds =4 withctisrcpos =Y to process only the CCD 4 where usually the bright source is located that causes the Out-of-Time events. ...

Next: Order Merging Up: Instrument Response Correction Previous: Using a Standard . ... It consists of a correction for the blaze function by using a suitable model of the blaze effect introduced by the echelle grating. ... This method uses the overlapping region of adjacent orders to estimate, in a few iterations, the parameter k of the blaze function which is, as before, assumed to be a sinc square. ... The method minimises the difference of the corrected orders in each of the overlapping intervals. ...

Geomagnetic storms and substorms are a natural hazard similar to hurricanes, floods etc. ... Solar and geomagnetic activity also probably influences the Earth's climate and human health. ... Under southward directed IMF the Earth's magnetosphere is open to input from the solar wind flow. ... Since practical importance of solar wind measurements was recognized, a number of approaches was developed for prediction of the geomagnetic activity basing on the solar wind data. ...

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 ...
