... 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 . ...

... 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. ...
