Presentation Transcript

  1. Image Reduction and Analysis Facility through the examples V SAR, Belgrade 2011

  2. - The need for astrophysical software - Linux ! V SAR, Belgrade 2011

  3. - IRAF: http://iraf.noao.edu/ - http://poincare.matf.bg.ac.rs/~donic/vezbe.html • Photometry & Spectroscopy • Reduction & Scientific analysis V SAR, Belgrade 2011

  4. The reduction of Echelle Spectra (just briefly) • Scientific analysis (spectral classification,…) V SAR, Belgrade 2011

  5. The Echelle Spectrum V SAR, Belgrade 2011

  6. The Echelle Spectrum V SAR, Belgrade 2011

  7. The reduction: • subtract the over-scan from all images • subtract the bias • trim the spectra • divide the spectra by the flat-field spectra • extract one-dimensional spectra • wavelength and flux calibrate the spectra V SAR, Belgrade 2011

  8. V SAR, Belgrade 2011

  9. Telluric and Helliocentric correction V SAR, Belgrade 2011

  10. V SAR, Belgrade 2011

  11. Analysis of the scientific data products V SAR, Belgrade 2011
