Image Analysis

Venturi With Purcell, Kramer, Baan
  • 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)
