Created NX(1) |
| ANTAB |
|
|
|
|
Used a nominal DPFU for Ho of 0.1. Grabbed Tsys values for Ho, Hh...I hope the Ho Tsys values are real Tsys values....they seem reasonable. For Halca used a Tsys of 88K, 92K. | |

Changed MNTSTA entries in the AN table. Changed Halca from 3 to 2, and changed Hh and Ho to 0. | |

AIPS Output Files
| Phase selfcal applied? | Yes |
| Global amplitude selfcal (gscal) applied? | No |
| Amplitude selfcal on non-global timescales used? | No |
| Modelfit made and saved? | Yes |
| Image Made and saved? | Yes |
| Comments on Difmap processing
Correlated in Jly 02', so no correlator amplitude correction were required. Do not have short spacings, so can't tell if the amp calibration is wonky or not. |
