line,nchan,start,width,stepThe default is all channels (or all wide channels if there are no spectral channels). The output will consist of only spectral or wideband data (but not both).
line,start,widthThe default is no reference line.
nocal Do not apply the gains file. By default, UVAVER applies the gains file in copying the data. nopass Do not apply bandpass corrections. By default, UVAVER corrects for the bandpass shape if the required information is available. nopol Do not apply polarizatiopn corrections. By default UVAVER corrects for polarization corss-talk. relax Normally UVAVER discards a correlation record if all the correlations are bad. This option causes UVAVER to retain all records. vector Means do vector averaging. This is the default. scalar Means do scalar averaging for the amplitudes and vector averaging for the phase. scavec Means do scalar averaging for the amplitudes of the `parallel-hand' polarisations (i,xx,yy,rr,ll). Vector averaging is used for the amplitudes of the cross-hand visibilities (q,u,v,xy,yx,rl,lr) and for the phases for all visibilities.
