Read in DQA1 delay and rate solutions. Used Hh as the REFANT. It had the only high SNR solution to Halca. | |
| TBIN |
|
|
|
|
Read in the DQA1 solns after I zeroed the delays and rates for the sole good DQA1 solution to Halca (so I can try FRINGing with no prior offset for Halca in case FRINGing with the offset does not work). | |

Try small windows at first...maybe I'll get luck and the DQA1 Halca solution is good. Results: No Luck |
| FRING | As above but with: DPARM(5) 1 Turn off LS. |
|
|
|
|
Try non-LS solutions.....no luck again. |
| FRING | As above but with: DPARM(1) 3 DPARM(2) 1000 DPARM(3) 50 DPARM(5) 0 GAINUSE 3 |
|
|
|
|
Try big windows with no prior offset for Halca. Results: Absolutely nothing for Halca. |
| FRING | As above but with: DPARM(1) 3 DPARM(2) 1000 DPARM(3) 100 GAINUSE 3 SOLINT 3 |
|
|
|
|
Maybe need shorter coherence time.... Results: Nothing |
| FRING | As above but with: DPARM(1) 3 DPARM(2) 200 DPARM(3) 100 GAINUSE 2 SOLINT 1 |
|
|
|
|
Try DQA1 offsets with short coherence time.. Results: Nothing |
| FRING | As above but with: DPARM(1) 3 DPARM(2) 500 DPARM(3) 200 GAINUSE 2 SOLINT 7 |
|
|
|
|
Try DQA1 offsets with the longest coherence time I could get without a memory error, and moderate sized windows. Results: Nothing |

The DQA1 report had also found some solns between Arecibo and Halca. I calculated what the approximate offset would be, and added this to CL(4). |

As above, with larger windows Results: Nothing...give up. amplitude |
