An anomaly was identified in the aria versions 8.0 and 8.1 when an image sequence template is added to a field in rt chart and a ciao (completely irradiated aperture opening) is calculated the resulting ciao display at 4ditc may be wrong. this results in a ciao which is in many cases larger than the actual largest extent of the irradiated area - possibly leading to an unintentional gap if that outline is used for edge matching of a second field.
