... While the resultant gains probably track the phase during the calibrator scan, what we are really interested in are the antenna gains for the program source. If you solved for a number of time intervals during the calibrator scan, the best guess at the antenna gains for the program source is derived by interpolating between some average of the calibrator scan gains. ... The task gpaver can be used to perform averaging of antenna gains. ... Average the gain table for the program source . ...

For example, the reduction program known as SNOPY, used for many years at La Silla and also at La Palma, uses a simple iterative technique in which some subsets of the parameters are solved for, while others are held fixed; then the ones last solved for are held fixed, while the ones previously fixed are redetermined. ...

The small variations in distance to the individual Cepheid variable stars in the Cloud are negligible compared with the much larger distance to the SMC. ... In this way Cepheid variable stars can be used as one of the 'standard candles' in the Universe that act either as distance indicators themselves or can be used to calibrate (or set the zero point for) other distance indicators. ...

... The chemically peculiar star HD965 belongs to a rare type of very slow rotators. As far back as in the 90s, G.Mathys (ESO, Chile) supposed its extremely slow rotation as observing split Zeeman components in the spectrum, from which he measured the magnetic field on its surface. Field variation proved to be very slow, and G.Mathys determined that the variability period should be longer than two years. ... Up to now, only two stars with periods longer than 20 years are known. ...

... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . The more we explore our Galaxy the more difficult it becomes to find static initial states. This leads us to study molecular clouds as dynamic in which initial conditions are neither prescribed or necessary. And this leads us to a new emerging paradigm which solves many of the nagging problems of the last two decades. The birth of stars is regulated by supersonic turbulence and its interplay with gravity. ...
