Intensity windows are time window files defined according to the count rate level of a
(or more generally the intensity level of an
HK time profile)
being in a given range. This range can be specified interactively in
a number of ways.
The main difference is that the value y1 above or below which is defined the acceptance, or
the couple of values y1 y2 inside or outside whose range is defined the acceptance, are specified
in the first case clicking the mouse respectively once or twice on the graphical representation of
a time profile present on a graphical window
in the second case entering manually the values and the name of the time profile to which they refer
Note that if there are gaps in the time profile, and if a good time window is open before the
gap, this will normally span over (enclose) the gap. If it is desired to exclude the gaps from
good time windows, the environment variable
can be used.
