Functions
each selection effectively specify the desired channel data in a specified spectral window If the user uses the FrequencySelectionChannel class then the selection simply selects a range of channels The other derived class is FrequencySelectionReferential which specifies a range of frequencies in a specified frame of	casa::vi::reference (e.g., LSRK).Unlike the other first method
FrequencySelectionUsingChannels 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 FrequencySelectionUsingChannels	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
