For Halca used a Tsys of 88K, 92K. For Mp used a nominal SEFD of 450 Jy. For Ka used a nominal Tsys of 171K, and a nominal DPFU of 0.26. For Ho, had Tsys vals around 170 (K). Assumed these are actually SEFDs/10 (although this is a little higher than what I would normally expect). | |

|
|
Used Mp as refant. |

|
|
|
Changed MNTSTA entries in the AN table. Changed Halca from 3 to 2, and changed Ho from 2 to 0. | |
| TBIN |
|
|
|
|
Read in DQA1 delay and rate solutions using antenna 5 (Mp) as the reference antenna. | |
| SNEDT |
|
|
|
|
Minor editting of DQA1 rate solutions. | |

|
|
|
|
Used a smallish SOLINT and largish DPARM(3) since the rates for Halca in the DQA1 report were fairly high. |
| SNEDT |

|
|
Minor editting. | |

Did not use gscale. Used a uv-taper to pick up some more diffuse emission. |
