    6 During calibration of the hawk sensor a noise and linearity measurement should have been taken, to identify these files look in the final capture spreadsheet under ~arsf/arsf_data/YEAR/misc/CAL_DAY, the entries that are used for the bad pixel generation are listed with a "Noise & Linearity" measurement. The files should be something like: NO1H1113, and have an integration time listed in the row; there may be some with a blue filter these can also be used in the detection of bad pixels.

    88There are 5 detection methods for finding a bad pixel:
     
    2727
    2828== Method C ==
     29'''__Linear Input Non-Linear Response__'''
     30
     31In the capture spreadsheet it should say the integration time for the file, this is used in this method. If the integration time against value is not above a certain threshold then it is considered bad, ideally it should be approaching 1.
