... 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.

... This is possible at modest cost due to the low moments of inertia of the telescope and enclosure. ... This same performance will be achieved in higher winds when the telescope enclosure is facing away from the wind, or by using wind screens. ... The telescope system (MILT) will be remotely operable with an on-site operator's assistance by an astronomer located at one of the ARC member institutions. ... Mean Wind Speed . ...

The FSP3 event includes those parts of the magnetic conjugations between any couple of four considered spacecraft, which satisfied to the FSP1 or to the FSP2 criterion. ... The value of the relative geocentric angular distance between magnetic field line's footprints is considered during FSP3 situation selection. The mentioned angular distance value less then 5 deg is used as a criterion of the magnetic conjugation. ... for the
