• No added counts on NDIT : In 2009-06 some dark setups have been acquired with a wide range of NDIT. The following setups have been taken:

    DET.DIT=1.6762 (= DET.MINDIT) 

    3 frames with NDIT=1
3 frames with NDIT=5
3 frames with NDIT=20
3 frames with NDIT=100
    The dark level was found to be (very) independent on NDIT
