    Fringes to Na in scans No0001 and No0003-6 in a single file:

    Na_fringes.pdf

     

    The first GMVA fringes to NOEMA after its upgrade. Single-dish setup, R2DBE, not NOEMA correlator output.

    In scan 2 two polarizations are IF0 and IF1, both correlated as "RCP" (and so both designated as R in the plots, be careful if printing or copying these!) for technical reasons. Because apparently the quarter-wave plate was inserted incorrectly, neither really represents RCP or LCP, as can be seen from similar SNR in correlations to LCP and RCP of other stations. The real polarization must be unknown elliptical or linear.

    In scans 1 and 3-6 "LCP" is IF0 and "RCP" is IF1. The polarization behavior is similar in all scans, SNR is approximately the same for LL, LR, RL, and RR.

    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.
