BW

BW specifies the bandwidths to use for the scan. One value can be given for each baseband channel. Any unset values will be set equal to the first so it is usually only necessary to specify one. These are used mainly for VLBA files, although the value will be written to VC commands in snap files. If not specified for a scan, the most recent value will be used. To get back to the default, (from the setup file), specify BW=0. The sign of BW traditionally has been negative for a net lower sideband. This is no longer required or even recommended.

• Argument: Up to one real number for each channel. The number is the bandwidth in MHz.
• Options: 0.0625, 0.125, 0.250, 0.5, 1, 2, 4, 8, or 16
• Default: Uses bandwidth from setup file.
• Usage: Uses the most recent value specified.
• Example: BW=2,2,2,2
