      adds a row of three zeros to the end of list (board) B. When you write createBoard, that row will have a name (maybe R), rather than hand-typed values. Displaying your 2d board of cells . You no doubt noticed that when Python prints a 2d list, it blithely ignores its 2d structure and flattens it out into one line (perhaps wrapping, if needed).

      Let Tfavg be the average of Tf1 and Tf2 to define the constant . Finally we define the N×N constant matrix with k, j = 1, …, N , and we calculate the N×N matrix . The desmeared image is then. with . In-flight tests have verified desmear by this technique using observations of Jupiter obtained at exposure times as short as 1 ms.
