| Abstract: |
An accurate sky subtraction technique for nebula slit spectra reduction is presented. The technique yields reduced spectra accurately baselined to zero flux, giving reliable emission line ratios for use in determining nebula properties, such as extinction from the Balmer decrement. The technique is automated, parallelised and incorporated into metaprogramming of reduction scripts. |
