Plateau de Bure Online Calibration

Some of the mentioned terms are partially estimated on real time so that the stored visibilities are already corrected from their contribution. Specific OBS commands, a dedicated GILDAS software package (RDI) and some CLIC procedures are used to produce and reduce the following scans:

Results from CALI and IFPB observations are applied to the data by the automatic data compression job. Corrections from tuning modifications are introduced in OBS by the operator just after GAIN, at the beginning of the observations. Therefore, in principle, amplitude errors should only be due to phase noise, pointing and focus errors.
