Pre-Processing:
WBPP for calibration
Batch format conversion of calibrated images with output with "compression-codec lz4hc+sh"
SubFrame Selection
Registration of all against best Ha Frame, output with "no-compression"
Integration of SHO channels with Automatic Normalisation
Linear Stage:
All S, H, O channels:
Dynamic crop of all to suit trim of combined data edges
ABE of each chn (Interpol function = 1, subtract, no normilization)
