It is scheduled for polarization correlation at 128 channels per baseband. Since I drafted the proposal it has become clear to me that the strength of the observational test could be improved further by taking Stokes I and V spectra from these data with much higher spectral resolution in a second correlation pass for (RR and LL only). As VY CMa is a very strong SiO maser source, we should be able to achieve an SNR and frequency sampling to permit comparison of theoretical polarization profiles over frequency, and provide further, orthogonal constraints on basic maser theory. I failed to include this second correlation pass request in the proposal and would like to make that request now. This would be in addition to the regular correlation pass in full polarization at 128 channel resolution. Thanks for your consideration.

However, the default correlator jobs should be checked, there are some lower-sideband mixes that USED to be handled incorrectly, and required hand editing of the frequency table. this MAY have been fixed.
