STEPPER takes a data cube (data) and allows a user to step
through the images and to display them as a movie. If the index
is passed in to stepper (as shown in 2 of the examples below) it is
possible to chose an option to display light curves.
Some sample calls are:
IDL> stepper, data
IDL> stepper, data, info_array
IDL> stepper, index, data, xsiz=512
IDL> stepper, index, data, info_array
where info_array and xsiz are optional parameters. xsiz indicates the size of the displayed image you want (must be an integer multiple of the the original array). It is a window driven program.
The use of the STEPPER routine is described in a little more detail in the User's Guide.
