SpectroCalc
SpectroCalc is a freeware for processing spectral exposures from the RAW data to the finished processed spectrum.

SpectroCalc is an easy to use and intuitive tool, which builds up the work-flow of the whole processing of a spectrum with following steps:
- dark frame correction (with master-dark builder)
- flat frame correction (with master-flat builder)
- interactive spectrum scan automatic
- interactive sky background remove automatic
- interactive continuums remove automatic (normalization)
- scan of reference lamp spectra with correlating parameters to the spectrum
- alignment automatic for single spectra with wavelength shift
- interactive wavelength calibration automatic
- post processing tool with different features:
- crop function
- EWA calculation
- S/N calculation
- heliocentric correction
- BeSS header parameter builder
- normalize function
- interactive telluric remover, with a possibility to correct single lines with extra parameters
The tool is designed to get a high accurate result with clear and transparent algorithms.
