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.
- Median Combine biases
- Upload background levels to sdb
- Upload overscan level to sdb
- Copy master bias to calibration directory
- 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
- 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
- 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
- Is subtracting off the master bias sufficient to correct overscan levels?
- The extraction needs to be improved.
