  • thr_rms_ADU = 10  – to discard very noisy pixels,
  • thr_min_ADU = 4  – to discard presumably dead pixels with 0-intensity,
  • thr_max_ADU = 10000 – to discard pixels with intensity significantly exceeding average value. To be on safe side for int16 data this parameter can be set to 216-4, where 4 in both cases is just a small arbitrary number for spare safety gap.

Example for module ImgAlgos::NDArrCalib

  • See  Module ImgAlgos::NDArrCalib, Module ImgAlgos::NDArrAverage

  • The NDArrCalib module in combination with PnccdNDArrProducer (or any other device NDArrProducer) can be used for evaluation of averaged pedestals or background using dedicated runs.
    Typical configuration file may looks like this:
