Analyzing direct imaging focus frames has now been made fun and easy thanks to the new kpnofocus routine. Simply run kpnofocus, giving as input the name of the focus frame. Next, mark the top image in a multiple focus exposure using the ``g" key. You will have to wait a few seconds, but you will then be presented with a plot of FWHM vs. focus value. Do this for a few stars and then exit using ``q". A This routine must be loaded from the nmisc package.
