1. Methods and instruments to measure/monitor major site properties
... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM).

9. Suppression of detector noise at low energies
... While there is practically no detector noise present at energies above , X-ray data below are considerably contaminated by noise events, which become more and more dominant towards the lowest transmitted energies (Fig. ... Investigations of 40 hours of in-orbit calibration data with the filter wheel closed, taken over a period of more than two years, showed that the noise properties vary with position and energy, but are fairly stable in time for most areas on the detector. ...

10. POLARIZATION PROPERTIES OF TWO PULSARS
Polarization properties of two pulsars R. N. Manchester (ATNF, CSIRO, Australia) . ... Abstract Mean pulse polarization properties at 1.4, 4.6 and 8.3 GHz and rotation measures are presented for two pulsars with unusually wide profiles. PSR J0437-4715 is a millisecond pulsar with significant emission over at least 80% of the pulse period. It shows a complicated variation of linear position angle across the pulse indicating substantial departures from a dipole field structure. ...

11. Generalized Spherical Harmonics for All-Sky Polarization Studies
... Consequently, it is inappropriate to expand and in ordinary spherical harmonics. The proper expansion expresses both and simultaneously in terms of a particular order of generalized spherical harmonics. ... Generalized spherical harmonics start at , and for each , . ... Generalized spherical harmonics obey a sum rule analogous to a familiar one for ordinary spherical harmonics, but it includes an explicit phase factor which depends on the orientation of the two lines of sight. ...

14. Period Analysis
Next: Period Determination . Period Analysis The combination of the X--ray and photometric observations have produced two samples of low mass PMS stars. At the time that the stars were monitored for rotational modulation, their photometric and spectroscopic properties were not yet known. ... By measuring the rotational periods of the stars in the two samples, one can separate out the effects of age on the rotation period from those of other factors such as mass.

17. Fractal properties of speech signals - ICND-96
... ICND-96, Saratov, Russia. ... And though a number of efficient methods of digital sound compression is developed by far, there is still a need in new efficient methods. In this report we study a possibility of application of fractal methods to compression of speech signals. ... In this method, a speech frame is divided into larger pieces called domains, and smaller ones called regions, and an optimal set of affine transformations of domains into regions is calculated. ...
