Dark current

After exchanging the NOTCam engineering grade detector for the science device it was noted that we still have an apparent very high dark current and excessive readout noise, in particular in the ramp sampling mode. From information obtain both from the ING LIRAS group and the manufactures of the detector, Rockwell, it became clear that the detector is not been operated in the optimum way and proposed changes to the wiring of the chip have been suggested to Preben Nørregaard. Currently we are waiting for his reaction.
