. Present section of the package enables one to perform following actions: . — . To make selection out of the total number of elements in accordance with the conditions imposed on some element or on a variety of elements. — . to sort the set of elements in order of ascending or descending value of any element. — . to draw the histogram of element distribution for obtained selection. — . To construct dotty picture of minor planet distribution in two– or three–dimension space of elements.
