Dear all,
	having agreed that we can use this forum for both the NIR and CCD 
worlds, I would like to hear your experiences of using the Rockwell HAWAII
arrays.

We have been running our science device and are experiencing
certain characteristics of the devices. Namely:-

1. even though we use off chip JFET source followers and short the on chip
FETs, we still see glow from a corner of each quadrant.

2. if we illuminate one quandrant with the dummy star, then we see a ghost
image of this in our other quadrants.

3. we see remenance type effects which decay over a period of minutes.

I know that many of you out there are experiencing similar sorts of
effects. I was wondering if any group has discovered ways and means to
reducing the above described effects.

				Regards,Derek
