... In order to detect sources the program computed the mode of the background, and then any pixel with a value greater than or equal to nsigma * backgound mode is considered to be likely associated with a source. ... Having obtained a source list, comprising their positions, sizes, counts and background counts, aperture-photometry is then performed on each source to produce a count value for each source that is consistent with the CAL calibration procedure. ...

. 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.

... The procedure of radiometer signal integration can be considered as a sort of reducing dimension of the initial sampling space, where the samples are the result of analog-to-digital conversion. ... The probability distribution of the signal and spikes is completely known. ... The quality of the considered algorithm could be also illustrated by Figure 2 . ... One could see the considered adaptive algorithm is preferable even by low degree of compression, because all spikes have been depressed. ...
