Catalogue details
- Two algorithms to detect candidates:
- Artificial sources added to measure completeness
- ‘MultiFind’ (Kilborn): 4? peak flux detection
- detection in 2 adjacent velocity planes
- Hanning smooth, repeat ? 2
- ‘TopHat’ (Howlett)
- cross correlate spectra with top hat filter
- repeat: filter sizes 1-40 velocity channels
- Candidate lists merged
- Automatic cleaning
- reject -300 < VGSR < 300
- reject lines at known interference freqs
- Interactive checking & parameter fitting
- accurate velocity, widths, fluxes
