Comment on a “Simple and Efficient Method to Eliminate Spike Noise from Spectra Recorded on Charge-Coupled Device Detectors”

Recently, Takeuchi et al. proposed a simple, so-called method for the efficient elimination of spike noise from charge-coupled device (CCD) data. In their paper, robust summation was shown to be advantageous in comparison to median filters, which had been occasionally employed to remove spikes from data recorded with CCD detectors.
