Spectral Line Radio Interferometry
Rob Beswick
Throughout, this lecture will primarily concentrate on Centimetric radio interferometry examples.
- Why do spectral line (multi-channel) observations?
- Brief outline of the science drivers
- Types of spectral line observations
- All future interferometry data will be spectral line data
- Planning & observations
- What do we need to consider
- Proposals & plannings
- Different spectral lines
- Velocity conventions (inc doppler tracking)
- Line experiment set-ups
- Identifing potential problems (& planning solutions)
- Resolution & brigtness sensitivity
- Data Analysis (specific to spectral line observations)
- Spectral bandpass calibration (theory & practice)
- Identification of RFI
- Gibbs Ringing
- Continuum subtratction techniques
- Deconvolution of spectral line data
- Anaylsis of line data (cubes)
- extracting spectra, moment analysis etc
