High Resolution 2.0 GHz producing one or few spectral windows with hybrid high-spectral resolutions and the rest of spectral windows with a uniform lower-spectral resolution. The total bandwidth coverage is 2 GHz for each of the sidebands. The data may contain some empty spectral windows in the 2GHz BW. 2.0

4.0 GHz producing 49 spectral windows in each of the USB and LSB data, the first window contains a single channel data that is the average of the rest 48 spectral windows data (or referred as Ch0). The rest of 48 spectral windows in each side band have a uniform spectral resolution. The total bandwidth coverage is 4 GHz for each of the sidebands. 2.3

ad hoc correlator modes producing number of spectral windows less than 49 by randomly skipping SMA correlator chunks in 4 GHz band. The correlator chunks have hybrid spectral channel resolutions. The script provides ways of mapping SMA spectral chunk's ID to the serial number of spectra in Miriad and features of handling the data with some of the spectral windows that may be filled with corrupted correlations. 1.1
