SALT/PFIS Reduction Software Outline Version 1.0

Operational:

• Focus run analysis
• Multi-slit peakup

Standard:

• Read FITS image
• Add keywords to FITS header of output file indicating each processing step that has been done. Maintain log file.
• Bias subtraction
• Dark subtraction
• Flat field correction
• Clean cosmic rays
• Bad pixel masking
• Multiple image registration
• Mosaic 3 PFIS CCDs into one image (correctly accounting for gaps)

Imaging:

• Astrometry solution
• Distortion correction

Grating Spectroscopy:

• Spectral line curvature & Distortion correction
• Wavelength calibration
• Sky subtraction
• Nod & Shuffle sky subtraction
• Extract long-slit spectrum
• Extract multi-slit spectra (should access original mask file)
• Establish spectrophotometric calibration from standard stars
• Apply flux calibration and extinction correction

Fabry-Perot Spectroscopy:

• ???

Polarimetry:

• Compute Stokes parameters
