each selection effectively
specify the desired channel
data in a specified spectral
window If the user uses the
class then the selection
simply selects a range of
channels The other derived
class is
which specifies a range of
frequencies in a specified
frame of 
casa::vi::reference (e.g., LSRK).Unlike the other first method
class Selects sets of channels
from a single MS The selection
is created by specifying a
sequence of channels in a
single MS By adding multiple
selections the user can select
any arbitrary collecton of
channels The order of the add
operations are unimportant
Imaging finds it convenient to
double specify the frequency
ranges first using an
MSSelection object and later
with a series of frequency
ranges The intent is that only
channels which match up with
both criteria should be a part
of the VisBuffer To accomplish
this first create a selection
using a
casa::vi::object (using method"add"with either an MSSelection or a channel range).When that is complete build up a FrequencySelectionUsingFrequency object to represent the various frequency ranges desired.Then use FrequencySelectionUsingChannels
