Reducing the Spectra

The main steps for reducing the spectra, along with the COSMOS routines used, are as follows:
  1. Create a spectroscopic flat field (Sflats)
  2. Flat-field and bias-subtract science exposures (biasflat)
  3. Subtract the sky from science exposures (subsky)
  4. Extract the spectra (extract-2dspec)
