Preprocessing Workflow

For each projection

• SUBTRACT_BACKGROUND

• CORRECT_FLATFIELD

  a division

• ZEROCLIPVALUE and ONECLIPVALUE

• DOUBLEFFCORRECTION

  • if logarithm is to be taken afterword : multiplication by the exponential of the doubleFF data

  • otherwise subtraction of the doubleFF data from the projection

• DO_CCD_FILTER

• DO_PAGANIN

• Longitudinal axis correction if they are contained in AXIS_CORRECTION_FILE (second column)

• TAKE_LOGARITHM [TAKE_LOGARITHM]
