cross procedure

The Cross 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. The available keywords for the cross procedure are shown in Table 2.

Table 2: Keywords available for the cross procedure. The keywords that are active depends on the selection of the sc.coordinatemode and sc.offsetcoordinatemode keyword values.
