    		 good weather, Tau225=0.24, but worsened towards the end of the observations, some thick clouds preventing pointing. Scan No0002 is probably the best.

    Notes

    PV has done parallel recording with the DBBC2 backend (PV) and the DBBC3 backend (P3). However the setup of the DBBC3 has been kept from the f191a test (4Gbps test) cariied out just before f191b. Since f191a was done in DDC mode the subbands are shifted by 16MHz with respect to the DBBC2 PFB bands (for details of the DBBC3 setup see the 4Gbps page).
    This means that 16MHz zoom bands have to be used when correlating with P3.
    For the following GMVA session the setup has been changed to match the DBBC3 subbands with the PFB subbands.
