peak procedure

The Peak procedure sweeps through the specified position in the chosen coordinate system in the four cardinal directions. Its primary purpose to deterime pointing offsets. Each sweep will be a separate scan with the Scan Length automatically determined by the coordinate Lengths and Rates. After the sweep along the major axis pointing corrections are expected to be entered in the pop-up window. After the pop-up window is closed the minor axis pointing will be done. This ensures(?) that the minor axis pointing will include the peak of the source flux. The available keywords for the peak procedure are shown in Table 11.


Table 11: Keywords available for the peak procedure. The keywords that are active depends on the selection of the sc.coordinatemode and sc.offsetcoordinatemode keyword values.
