| Abstract
No Fringes were found to Halca, while strong Hh-Mp Fringes were found for visibilities on the U-V plane near Halca-GRT visibilities. Suggest re-scheduling this experiment. |

These are the standard parameters I used (unless otherwise specified). No Halca fringes were found in the DQA1 report. Hh-VSOP U-V points around 0 9 30 0 0 10 20 0 are pretty close to Mp-Hh UV points (where strong fringes were found!), so use this as a test-bed for finding Halca fringes. |

Strong Fringes for Mp-Hh (as expected), but still no Halca fringes.....give up on Halca. |
