... As mentioned in Section 5.4 , many Miriad tasks allow a range of channels to be given by their velocities (rather than their channel numbers). ... The velocity specification is given in the form line=velocity, nchan , start , width , step or line=felocity, nchan , start , width , step where nchan is the number of velocity channels to select, start is the centre velocity of the first channel selected, width is the width of each channel, and step is the velocity step between channels. ...
