... We have made observations of the Perseus cluster with the Westerbork Telescope at 610 MHz. ... Several newly detected sources are identified with cluster galaxies. ... No evidence is found for the existence of the previously reported ~ 65'x25' cluster halo, 3C 84B. Key words: radio galaxies - clusters - tailed radio sources buoyancy The Perseus Cluster of galaxies is one of the most fascinating systems accessible to extragalactic astronomers. ...

... The algorithm has been successfully applied to both real and simulated astronomical data (Jefferies , 1993; Jefferies 1993) and its ability to accurately preserve photometry in the observed image has been demonstrated. ... In order to investigate the algorithm's performance without the influence of detector and photon noise we took the ``truth'' data set and convolved it with the given PSF to generate a noiseless image. ... The restored object and the two restored PSF's are shown in Fig. ...

If withoutoftime =y the task does not create the ``normal'' events file but uses the input file instead to create an event file where all events are treated as out-of-time events. ... Similarly, for Full Frame and Extended Full Frame modes (currently) the 11 rows closest to the CAMEX are set bad onboard but sources in these rows may also cause unrecognized out-of-time events. ...

... Ultraluminous X-ray sources (ULXs) are located in external galaxies, their X-ray luminosities (10 39 - 10 41 erg/s) are thousand times greater than those of brightest black holes in the Galaxy. ULXs may be supercritical accretion disks around black holes of stellar masses (~10 Solar masses) like that in SS433, or they may be a hypothetical intermediate-mass black holes (hundreds - thousands Solar masses) with standard accretion disks. ... 2) The ULX progenitors were ejected from the star clusters. ...

... Structure of Data . ... Catalog . ... In SAI OCL Catalog, we introduce our work on investigation of the Milky Way system of open star clusters. The main goal of our study is a search for new clusters using huge surveys. 168 new clusters have been already discovered by us using J,H,Ks data from 2MASS point source catalog. ... For 141 new clusters, we found their physical parameters using J,H,Ks data from 2MASS catalog and, for a number of clusters, our UBVRI CCD observational magnitudes. ...

CIMA configuration files offer You a conveniant way of saving CIMA set-ups to files. ... Then instead of making this selections interactively when You are observing, You can just load and apply the configuration files. ... Any other set-up will be ignored! ... In that case, You are forced to use the 'Load only' option to load the configuration file, inspect the selected set-up carefully, apply the set-up (with the 'Accept' or 'Apply' buttons) and then save a new version of the configuration file. ...
