Calibration of radio data
Neal Jackson
Need for calibration.
Quantities to be calibrated:
flux scale,
elevation,
phase calibration,
bandpasses,
pointing,
polarization,
fringe finders.
The enemies:
troposphere,
ionosphere,
correlators,
severity of the problems,
effect on different types of array.
Smearing:
choice of bandwidth and integration time.
Useful calibration sources for each type of calibration.
Calibration strategies.
Some examples for different interferometers, frequencies, types of observations.
Self-calibration.
Calibration software.
Brief description of calibration strategies in AIPS.
Very brief description of calibration in CASA.
