Subject: M1606 
On Friday I have tested M1606 at room temperature in the red cold box.
Previously it was reported that trimming does not work for ROC2.

In this test trimming was fine, only 11 pixels failed it.
See the attached 1D and 2D histograms. There is small side peak at about vcal=56 with ~100 pixels.
But this should not be a too big problem?

Also the Pulse height map looks good and the reconstructed pulse height at vcal=70
gives vcal=68.1 with rms=4.2, see the attached plot.

So I conclude that this module is fine.
