Image analysis tutorial outline

• Evaluation of the image quality
  • Overall look at the image and estimate of the rms (TVSTAT)
  • Standard plots (CNTR/KNTR)

• Observational measurements
  • Flux density measurements of a compact component (IMFIT/JMFIT)
  • Flux density measurements of an extended component (TVSTAT)
  • Total spectral index

• Slices along the structure (SLICE/SL2PL/TKPL)

• Going from flux densities to monochromatic radio powers

• Spectral index
  • Matching uv-coverage
  • Matching images
  • Spectral index images (COMB)
