pynrc.reduce.calib.calc_ktc(bias_sigma_arr, binsize=0.25, return_std=False)[source]

Calculate kTC (Reset) Noise

Use the uncertainty image from super bias to calculate the kTC noise. This function generates a histogram of the pixel uncertainties and takes the peak of the distribution as the pixel reset noise.

Parameters

  • bias_sigma_arr (ndarray) – Image of the pixel uncertainties.

  • binsize (float) – Size of the histogram bins.

  • return_std (bool) – Also return the standard deviation of the distribution?
