We have been running smoothly with the engineering grade array since May 2006. The new science array arrived in October and is still in storage (in dry conditions), waiting for the upgrade of the electronics before installation and commissioning. This should happen as soon as possible since we expect it to be more sensitive and flatter than the engineering grade array.
Bad pixel maps for the engineering grade and the failed science grade array are available on the web.
Data has been taken to determine the plate-scale for the high-resolution camera but the data still needs to be analyzed.
