Procedures/OwlProcessing
v31 v32 84 84 During the radiometric calibration blinking pixels are tested for and removed from the data. It is likely that the default settings will not remove all the blinking pixels and the data will have vertical stripes. To remove these reprocess with a lower value of pixstabi e.g. 85 85 86 process_OWL_line.py -p <project directory> -f <flightline> -m pixstabi=0.00586 batch_cal_owl_proctool.py -p <project directory> -f <flightline> -m pixstabi=0.005 87 87 88 88 The pixstabi modifier defines the standard deviation of the time series allowed for a normal pixel, so reducing this removes more pixels above this range. It is not expected that all blinking pixels can be removed as the blinking pixel routine does not yet appear to be optimal. Do not make the value too low as this will remove too many pixels and result in thick vertical stripes where the data has been replaced. It will also remove a considerable amount of spectral information, so check that the spectra still look reasonable. Somewhere between the first 2 images below is desirable.
