... region (region-7.9.3) [xmmsas_20080701_1801-8.0.0] . ... 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. ...

... User Guide ] Task: imstat Purpose: calculate and plot map statistics Categories: map analysis IMSTAT calculates statistics for images. ... Statistics can be found for profiles or planes, specified using the axes keyword. The data can be converted to Kelvin, by using 'options=tb' and the beam keyword. ... The options keyword gives control over the plot. ... An alternative title can be put on the plot by options=title. ... Key: in Standard keyword in. ... Key: region Standard keyword region. ...

The srcinten task provides PROS users with a tool to compute count rates for point sources in the ROSAT High Resolution Imager (HRI). ... Corrected upper limits are cited at locations where the count rate falls below the source detection threshold. ... Srcinten is a new PROS task that computes and applies the above correction factors to the net counts in a user-specified aperture. ...

... As described in "Tabular Storage of STIS Data" on page 20-5 , raw time-tagged Sdata are stored in an event table which contains separate columns for the x and y pixel coordinates and the arrival time of each detected photon event. ... Generate a series of ACCUMulated images from user specified time intervals of data and then process the image(s) with calstis . ... The default behavior for inttag is to accumulate all events from the table, writing the results as one image set in the output FITS file....

Pulkovo NEO Page . ... EPOS Software Package . ... EPOS ( E phemeris P rogram for O bjects of the S olar system) is the Windows PC application for study and ephemeris support of observations of the Solar system objects. ... It controls the part of common data and transfers the control to one of the programs that solve the restricted set of tasks. ... So with the EPOS software package one can calculate the accurate ephemerides for many objects and get the quick illustration of their motion as well. ...

... Restrictions ) are used. If specified form of output is EMP then astrometric equatorial coordinates are printed in the form usual for Ephemerides of Minor Planets, with formal precision of 0.01 minute of time in R.A. and 0.1 minute of arc in declination. ... It should be noted that the near-opposition ephemerides are not calculated for bodies/ points with numbers from –12 to 0 (in case they are included into task for computation of such ephemerides only their names are displayed in the results). ...
