In this example the image is stored as a vector in column 2 of the table where each row of the table contains a different 300 x 200 pixel image of the same object (taken at different times). All the coordinate system parameters are the same for each image and are given as header keywords, except that the MJD-OBS column gives the date corresponding to the image in that row.
