... Return the telescope effective area in square cm averaged over the given energy band and at a specified position in the telescope field of view. ... the effective area at any position in the field of view is calculated from an on-axis effective table and from a set of vignetting tables provided in the CCFs. The vignetting tables are normalized to one on-axis and are provided as a function of the off-axis angle for energies ranging from 100 eV to 15 keV. ...

. This diagram shows a small table with three transparent cells and illustrates how their final background is determined. The table consists of two rows. Four (labeled) cells lie in the first row, but the second cell spans the first and second row. The first, third, and fourth cells of the second row are "empty". Each non-empty cell has a red background and a double black border. Each empty cell has the table's background color (specified as #ff0) as its own. Return to image.
