... The amount of energy encircled by an aperture used for stellar photometry will depend on both the aperture size, and also on any variations in the PSF with field position, time, etc. ... The differences in photometric magnitude between apertures with various radii (i.e. aperture corrections), and their mean and standard deviations for the F555W filter, are presented in Table 5.5 . ... Variations in the PSF with field position will, of course, cause a position dependence in the aperture corrections. ...

... The task calculates an average RMF over the spatial region used to extract the source spectrum. ... Essentially a grid is placed over the source region and the redistribution parameters calculated at each point. ... By means of command line parameters the averaging may be performed assuming that the flux distribution is that of the point spread function (PSF), a flat uniform distribution or it may be defined explicitly by supplying the task with an image containing the source region. ...
