... Archives . ... If you do not mind the time predictor, it is hard to believe that this is a light curve, time dependent data. ... It?s hard to say this data set is designed for time series analysis apart from the complication in statistical inference due to measurement errors. How to design the statistical study with measurement errors, huge gaps in time, and unequal time intervals is complex and unexplored. ... The following is R output without measurement errors. ...

... Let us first find out which way -- rise in spectral resolution with some loss in the S/N ratio or increase in the S/N ratio with a fixed spectral resolution -- is better for the purpose of reduction of equivalent width determination errors. ... N -- number of counts for 1 ? ... line equivalent width, . ... Thus if the spectral resolution is managed to be increased (i.e. to decrease )without loss in the number of counts falling at 1 ?, the equivalent width measurement error is then proportional to . ...

The aim of this section of the course is to enable you to use simple computer programs to solve a variety of common astronomical tasks. ... I have (somewhat arbitrarily) decided to use Python for this course, because it seems to be gaining popularity fast for astronomical data handling, and because some of you will have encountered it at the ATNF course. ... We've put Python (plus all relevant libraries) on the Stromlo Linux computers moron and maggot. ... Now log in to moron (or maggot). ...

... These experiments followed the movement of the subreflector as the antenna tipped from the zenith to the horizon. We find, relative to a coordinate frame attached to the receiver platform : ffl The axial movement (axial defocussing) is 0.7mm ffl The lateral movement, (in the focal plane, normal to the elevation axis) is 2mm, and no move­ ment parallel to the elevation axis. ffl A rotation of 3 arcminutes about the elevation axis. ... This gave the rotation of the subreflector, shown in figure 3. ...

... The first of the equations defines the position of the spectral orders, m , in the raw image, while the second equation gives, for each order, the dispersion relation in one dimension. ... where the coefficients are computed using least squares techniques on a grid , i.e. sample number and line number of points located within the spectral orders of the image. These points in the grid are found automatically by an order--following algorithm, normally using the FLAT or STD image. ...

... A document window is shown, with 8 lines (numbered 1 to 8), each 24px high. The text of the "outer" box (at the end of line 1, halfway into line 2, and halfway into line 3) is shifted upward 12px. The text of the "inner" box, thought shifted upward as well, has been relatively positioned so that it lies in its normal flow position at the end of line 2. ...

... Information about a variety of different calendars for different cultures (e.g., Christian, Jewish, Muslim, Chinese, Hindu etc.) ... 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 ...

... The experience of determination of the link between radio sources and dynamical reference frames is presented. To obtain this connection we used a series of very long baseline interferometry (VLBI) observations of the spacecraft Phobos-2 and angularly nearby quasars. ... The dynamical reference frame is determined by equator and equinox of these ephemerides. ... References . ... The relative orientation of the radio and dynamical reference frames can be described by a sequence of three rotations . ...

This widget allows you to offset the telescope. ... Offset type : one of "Object Arc", "Object Arc XY" or "Boresight". ... This is motion on the sky or instrument, so don't worry about cos(dec). ... If you want to move that point (e.g. center your object along a different bit of the slit), then use a boresight offset. ... Note that a +X object xy offset will move the sky in the -X direction on the focal plane, because you are centering something in the +X direction on the boresight. ...

Now we consider qualitatively the effect of the electromagnetic field of a magnetic rotator on the accreting plasma. ... What is important is that both relativistic particles and magnetic dipole radiation will transfer their momentum and hence exert pressure on the accreting plasma. ... 2) The pressure of the accreting plasma is high enough to permit the plasma to enter the light cylinder . ...

... Low Polar Orbit . ... Different types of satellite orbits have different uses: while the synchronous orbit is best for communication satellites, Lagrangian point orbits help monitor the solar wind before it reaches Earth. ...

If the satellite then starts near a noon-midnight orbit, it will always pass near noon and near midnight. ...

... Using the uvby -photometry and proper motion data for about 5500 F stars within 80 pc from the Sun, we have studied velocity ellipsoid parameters and obtained the following results. 1) The sizw of all wllipsoid semiaxes increase systematically for groups of stars with the decrease of both temperature (at constant metallicity) and metallicity (at constant temperature). ... As a result, each of the three parameters - temperature, metallicity and velocity dispersion - is an age indicator. ...
