Standard Calibration

This tool is designed to calibrate a standard NOEMA project. The name of the `hpb` (header) file must be specified in the `Standard Calibration` widget (Fig. ) to start. A limited scan range can be selected to perform a complete or partial calibration. By default all the scans are considered. The receiver band used in the observations is determined by clicking on `Select`.

The calibration must be done by clicking on the proposed steps from left to right. `Select` is so needed at first, and also before repeating any part of the calibration. The last option `Print` combines all the postscript files created of each calibration step in a single file called `date'-`projectname'.ps. This package is an interactive tool which pauses for an input from the astronomer. It is not recommended therefore to click on the `GO` (see Sect. ).

The option `Use previous settings` (in the widget; Fig. ) permits to adopt settings coming from a previous calibration of the selected `hpb` file, with respect to the atmospheric phase correction, scan ranges, selected bandpass calibrator, etc.

Finally, note that all the plots created within the `Standard Calibration` are presented for logical antennas, which are sometimes different from the physical ones shown in the `First Look` outputs (see Sect. and App. ).
