filter intensity

After you have made a light curve, you can enter intensity selections, given as a range of acceptable values. The scale for intensity is read from the plot given in PLOT CURVE. The task converts this intensity selection to a set of GTI's, which are passed to the next EXTRACT run.

So 

xsel > filter intensity .1-1.5

will PASS only those bins with an intensity between .1 and 1.5.

For v2.5b this task was modified to run using the ftool mkintensfilt instead of the ftool maketime for better handling edge effects.
