1. Calibration Scans
Next: CORRELATOR BOARDS Up: OBSERVING PROCEDURES Previous: Frequency Switching . As with any type of observing, it is always a good idea to run a few calibration scans at the beginning of, and during, your observing run to make sure that the telescope and receiver are behaving properly. At Arecibo this is done by performing a ``spider scan" (a pattern of four scans across an object, each separated in position angle by 45 ) on a standard calibration source. ...
