Next: About this document Up: Evaluation of Image Restoration Previous: Methodology . Table 1 summarizes some distance measure results. ... Visual inspection alone showed that the three algorithms: R-L, MEM0, and ILS+ are capable of very similar results. ... Preliminary results from an ongoing study of photometric errors from aperture photometry in restored images suggests that restoration by R-L, MEM0 and ILS+ does not degrade the random error level in large-aperture photometry of isolated stars. ...

The first thing to note is that Twitter does not guarantee to return all matching Tweets, whatever method is used (unless you have direct access to their "fire hose", which I don't). ... This should result in the same results as my REST-based search (method 2), since the volume of Tweets was probably not enough to cause this site to miss Tweets based on their collection strategy . ... A search for the tag #aas219 (case insensitive) using the Twitter REST API . ...

... The removal of the bright sky background from your IR images is one of the key steps in the data reduction process. Once bad pixels have been removed from all the astronomical frames, the object frames must have the matching sky background images subtracted from them. ... The simplest sky subtraction is where you have separate sky and object frames taken a short time apart. ... The resulting sky subtracted images should be examined to make sure that sky subtraction has been properly achieved. ...

Some recent results ( see ) attracted the attentions of astronomers working on field which could benefits from photon counting techniques with high speed and spatial resolutions as adaptive optics. ... Fasti has been designed to be fast and largerly configurable. ... The data rate attined in the best case (30 Mhz), give no impossible load to the digital acquisition in the photon counting mode, since data are 1 bit only, they can be parallelized, giving a maximum speed of about 940.000 32 bit word/sec. ...

Consistent relativistic formulation of Earth rotation (Gerlach, Klioner, Soffel) Status of the numerical solutions - 2 Ї The results from numerical solutions suffer from ґ Simplified solid Earth models ґ Incomplete Earth system models or neglecting of certain parts or neglecting of certain coupling mechanisms ґ Methodological limitations of computations...

... The improvement will be more pronounced in our crowded Wide Field Camera (WFC) images, and may be increased further through use of a more sophisticated method of combining the individual dithered images. Our analysis allows us to check for point spread function shape variations in the HST Planetary Camera (PC) field. ... In crowded field images, we are deriving information about the faint end of the luminosity function (LF) from the texture of the image background. ...

... The eboxdetect task has two different modes of operation: (1) local detection and (2) map detection. eboxdetect is first run in local mode. The local mode source lists serves as input for task esplinemap which creates background maps (one per energy band for each EPIC instrument) which are then used to run eboxdetect in map mode. ... In both modes, source searching is only performed in the area of the images which is marked by an optional detection mask created by task emask . ...

The results are written to /home/alfa/realtime/results on the ASP but are best viewed through the php web server (see below). ... Start the processing. ... Notes on the Candidate Viewer ----------------------------- The candidate viewer can be run from any browser on any computer on the AO network, not just ASP. ...

Correlated flashes of masers H2O . ... In 1981 - 1982 years it was revealed several Flashes of maser radiation of H2O radioline at wavelength 1.35 cm in the radio-sourse W49, developing practically synchronously at several radial velocities. It's known that components of the maser radiation of H2O radioline profile with different radial velocities arise in separate spatially diverse areas of a starformation. ...

... The most precisely determined characteristic for accreting neutron stars (NS's) is their period. ... Period changes show fluctuations. ... Some applications of stochastic processes in astrophysics especially in accreting systems were discussed in Lipunov (1987),Hoshino Takeshima (1993) and Lipunov (1992).In Hoshino Takeshima (1993) the authors, using simple models of MHD turbulence, try to explain aperiodic changes in X-ray luminosity of X-ray pulsars. ... Here, -constant angular momentum. ...

... A three-cell test section roughly representative of the primary mirror was provided for this test by the Steward Mirror Lab. ... Additionally, the tests are intended to determine relative airflow vs. pressure drop characteristics for each of the air flow patterns so the results can be evaluated both as a function of flow rate and of pressure drop along the flow path. ... The bottom (top as installed) was cut out so it could close the chamber for heating and be removed for the cooling tests. ...

... Moscow, Russia E-mail: krivosheev@iki.rssi.ru Notes: Ї Ї The Monte Carlo method (s) is also called the statistical test method An innumerable number of processes can be listed the outcome of which is not determined and has probabilistic nature, but these processes obey statistical laws, so to obtain the result we have to make multiple similar tests, i.e. to use the MC method Because probabilistic processes are widely spread in nature, the MC ...
