... User Guide ] Task: mbspect Purpose: Make spectrum and measure velocities from a Miriad image. ... MBSPECT makes a spectrum of the velocity or frequency axis of a Miriad image. ... No default. ... Spectral units are always in the same units as the input file (even if a conversion is performed for the plot and/or log file). ... A second value will overwrite the default label for this axis. ... Key: order Order of optional robust (clipped polynomial) fit (0-10) to be applied to the spectral axis. ...
