simulator.setspwindow

Set one or more spectral windows

Synopsis setspwindow(row, spwname, freq, deltafreq, freqresolution, nchannels, stokes)

Description Set one or more spectral windows for the observations, including starting frequency, number of channels, channel increment and resolution, and stokes parameters observed. Can be invoked multiple times for a complex observation. Must be invoked at least once before create.

Arguments

`row`	Row number in the spectral windowg table
	`Allowed:`	`Int`
	`Default:`	`1`
`spwname`	Unique user-supplied name for this spectral window
	`Allowed:`	`String`
	`Default:`	`'XBAND'`
`freq`	Starting frequency
	`Allowed:`	`Quantity`
	`Default:`	`'8.0GHz'`
`deltafreq`	Frequency increment per channel
	`Allowed:`	`Quantity`
	`Default:`	`'50.0MHz'`
`freqresolution`	Frequency resolution per channel
	`Allowed:`	`Quantity`
	`Default:`	`'50.0MHz'`
`nchannels`	Number of channels
	`Allowed:`	`Int`
	`Default:`	`1`
`stokes`	Stokes types to simulate
	`Allowed:`	`String`
	`Default:`	`'RR LL'`

Example

To simulate a two spectral window (or two IF's in VLA jargon) data set, use setpwid as follows (here we are simulating 16 channels, 50MHz wide channel for each spectral window)

mysim.setspwindow(row=1, spwname='CBAND', freq='2GHz', deltafreq='50MHz',
                   freqresolution='50MHz', nchannels=16, stokes='RR LL');

mysim.setspwindow(row=2, spwname='SBAND', freq='5GHz', deltafreq='50MHz',
                   freqresolution='50MHz', nchannels=16, stokes='RR LL');

Note that the spwname is just a label and should be unique.
