These are the specification for the reduction of HRS observations for the pipeline. This includes data quality measurements as well as reducing and distribution calibration and observational data.

Bias Reductions

• Median Combine biases
• Upload background levels to sdb
• Upload overscan level to sdb
• Copy master bias to calibration directory

Flat Reductions

• Subtract master bias
• Median Combine flats
• Upload background levels to sdb
• Upload overscan level to sdb
• Create Order frame
• Upload order positions to sdb
• Copy master flat to calibration directory

Arc Reductions

• Subtract master bias
• Median Combine arcs
• Extract object fiber
• Extract target fiber
• Upload background levels to sdb
• Upload overscan level to sdb
• Identify/match lines in each order
• Upload match lines to sdb
• Calculate 2D Wavelength solution
• Copyw wavelength to calibration directory

Science Reductions

• Subtract master bias
• Apply flat correction
• Upload background levels to sdb
• Upload overscan level to sdb
• Extract object fiber
• Extract target fiber
• Normalize extracted spectra
• Subtract sky from extracted spectra
• Stitch spctra together
• Apply Wavelength solution
• Vacuum to air correction
• heliocentric correction

Radial Velocity Reductions

Spectrophotometric Standard reductions

Questions/Improvements

• Is subtracting off the master bias sufficient to correct overscan levels?
• The extraction needs to be improved.
