Hi Lisa,

The second correlation pass is aimed at only the RR and LL
correlations, at higher spectral resolution than cross-polarization
allows, so I'd like to request:

a) RR, LL, all IF's, 2s integration, 256 channels => 900 kB/s

If you can process RR and LL separately, then we could go
to 512 channels, but it would require an additional pass.

Thanks,
Athol
