The center of the area is chosen interactively with the cursor from the plot displayed by the MODIFY/OPTOPUS command. After the zooming, a cursor again enables the user to select objects in wrong position so that they can be rejected by typing a "D" letter (uppercase or lowercase) when a prompt appears. (See also documentation to MODIFY/OPTOPUS command). \up\sy Syntax: ZOOM/OPTOPUS [table] [zooming_factor] \ys\pa [table] = input table of HOLES/OPTOPUS command which contains :RA and :DEC columns and refers to the drawing of the Optopus plate plotted by the MODIFY/OPTOPUS command. Default name is "opto1.tbl". \ap\pa [zoom_fact] = Factor used to enlarge the chosen area of the plate. Default is 5. \ap\no Note: If after the first zoom one realizes it is not enough or too much, it is possible to use again the command ZOOM/OPTOPUS only changing [zoom_fact] and without having to issue again MODIFY/OPTOPUS to re-plot the Optopus plate and subsequently choose the center. \on\exs Examples: \ex ZOOM/OPTOPUS myoptotab 5 \xe\ex ZOOM/OPTOPUS ? 10 \xe\ex ZOOM/OPTOPUS myoptotab 10 \xe\sxe
