The following recommendations are made:
At line 21 added 11 lines
# Scientists should always use interpolated intensities and errors for missing pixels when analysing EIS data. Significant errors may result if missing pixels are simply ignored, particularly as the number of warm pixels on the detector increases.
# The method for interpolating the intensity of missing pixels in EIS_PREP should be modified.
# The error bars assigned to interpolated data points should be estimated through comparison with non-missing pixels, but modified according to how the interpolated intensity value was derived.
# Accurate re-creation of line fit parameters appears to be possible even up to the case of 30 % warm pixels. This corresponds to a lifetime of around 6 years considering the current rate of increase of warm pixels on the EIS detectors.

! Update
The method described above has been incorporated in EIS_PREP as an option: it is called through the /refill keyword.
