... region (region-7.9) [xmmsas_20070708_1801-7.1.0] . ... The basic source region shape is a circle. There are three ways to assign the radius, specified via the parameter radiusstyle : . radiusstyle =`userfixed'. ... In this choice, the task uses for the source region radius that value which encloses energyfraction of the total flux under the Point Spread Function (PSF). ... At present the effect of this reprojection on the source region contours is ignored and circles are retained. ...

... This section will deal with obtaining photons within specified regions of an image. Available regions are: Annulus Box Circle Ellipse Field -- entire field Irregular region based on intensity of map... i.e. region defined by contour levels. ... The imcnts task in the xray-spatial package sums the source and background counts in specified regions, and subtracts one from the other properly normalized. ... imcnts* - Find counts in an extended region, after removing an embedded point source . ...

Next: SRCCAT Up: Details of SCHED Parameters Previous: SETUP Contents . SOURCE is used to specify the source name. ... The name must match, in a case-insensitive sense, one of the names of a source in the source catalogs (recall that 5 different names or aliases are allowed for each source). SOURCE may be the name of a Solar System object. ... The Solar System objects that SCHED understands are Mercury, Venus, Moon, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, and Sun. ...

... Up: Science Data Pipelines . ... We designed and developed a package which simulates extragalactic point source data within a given field of view and SIRTF band. ... The simulator is modular and extensible to enable multi-wavelength simulations, has been optimized by utilizing parallel processing capabilities, and will be used to test pipeline software. ... The extragalactic simulator is capable of generating large numbers of galaxies within a given patch of sky for SIRTF pipeline testing. ...

... 88, Jan. 1983, p. 1-15. l. A survey of extragalactic radio sources made using driven declination scans is reported covering an area of about 0.07 sr to a limiting flux density of 35 mJy. The fast-scan survey was carried out at a galactic latitude greater than 17 deg with the NRAO 91-m telescope operating at 4.755 GHz, and the 480 sources detected were reobserved at 1.4 GHz with the National Astronomy and Ionosphere Center 305-m telescope at Arecibo. ...

... Up: Description of program searchdup Previous: Program use . Input records are ordered per date of observation, and the list of known (observed) sources is cleared. Each record is compared in position to all the known sources. If the sky distance is less or equal to the specified one, the record is added to the list of observations for that source. If no known sources are within the specified radius, a new source is created, with the coordinates of the observation record. ...

... All the parameters provided in this database have been obtained using the the MIRIAD ( Sault et al. 1995 ) task MBSPECT . MBSPECT makes a spectrum of the velocity (or frequency) axis of a cube. The spectrum is beam-weighted, over the width specified, for the other image axes. ... Robust parameters are calculated by using an algorithm which minimises the mean absolute deviation of the flux-weighted velocities. mask= This specifies the x-axis ranges to be excluded from any continuum fit. ...

... The quickest way to learn how each observation was performed is to use the iminfo task in the STSDAS toolbox.headers package to look at the headers of the science data. ... Number of extensions . ... Given that NICMOS data files contain multiple extensions, the number of the desired extension must always be specified. ... In order to simplify access to NICMOS FITS image extensions, each extension header contains the two keywords: EXTNAME (extension name) and EXTVER (extension version number). ...
