Message:

Removed name_ related fields and functions.
Changed getTime to sprint out string of MVTime.
Added range checks for setIF/Pol/Beam functions.
Added const to get type functions, where it was missing.
Removed debugging cerr from getAbscissa
Added setCoordinate to set the Frequency Table from SpectralCoordinate?.
Added nScans()
Added more info printing to summary
