smablflag - is an interactive flagger; plots a baseline as a function of time and flags bad points using the plotting cursor (color coded for source). smacheck - examines uv variables for SMA data and flags uv-data if variables or data are out of range. smauvplt - plots visibility data (color coded for sources) as a function of time and other variables (used for non-polarization data). smauvspec - plots SMA spectra (color coded for chunks); reads JPL spectral line catalog and plots molecular transitions along with SMA uv spectra. smavarplt - plots variables vs variables (color coded for sources).Descriptions of the keywords in the SMA routines ( smacheck, smauvspec, smauvplt, smavarplt, and smablflag) can be found from the inline documentation.
