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. ...

Next: Inspection of results Up: *fit* - Fit Data Previous: Verbose Mode . If the number of net counts for a source is less than it is impractical to fit the data in all 34 energy bits. However, if the flux is required, then a fit must be performed first. ... Fit will then calculate the normalization of the model and xflux can be used to determine the flux and luminosity of the source from the best fit model. xs> fit rebin=yes . ...
