... Omdetect classifies a source as being extended if its computed semi-major axis is greater than that of the point-spread function's semi-major axis (computed by using moments), by at least twice the error computed for the former. ... 1) The quantities the total raw pixel counts, total corrected raw pixel counts and the total raw background counts are initialised to zero. ... d) The total raw background counts is incremented by the value of the corresponding background-image pixel. ...
