nod procedure

Nod does two data integrations in an one 1st beam on 2nd beam sequence. The 1st beam and the 2nd beam are defined by the user. The times spent observing on each beam is the same. The available keywords for the nod procedure are shown in Table 16.

Table 16: Keywords available for the nod procedure. The keywords that are active depends on the selection of the sc.coordinatemode and sc.offsetcoordinatemode keyword values.
