CSV2017:Final check of radio pointing offsets in BAND8 and DASH345

CSV2017:Final check of radio pointing offsets in BAND8 and DASH345†

↑

Tasks†

↑

Preparations†

Basic checks
- Make sure that DASH3 and BAND8 are linked to the following files
```
[aste17@aste-ms1 ~]$ ssh astecntl@aste-1c "ls -l /cosmos3/aste/etc/kisag/{DASH3,BAND8}"
lrwxrwxrwx 1 astecntl astctl 12 May 31 07:58 /cosmos3/aste/etc/kisag/BAND8 -> BAND8.170531
lrwxrwxrwx 1 astecntl astctl 12 May 31 07:33 /cosmos3/aste/etc/kisag/DASH3 -> DASH3.170531
```
  - If not, contact with CSV lead.
- Set all subref parameters (dx,dy,dz,dtx,dty,dtz) zeros in the subref offset GUI.
- Confirm that Aspirin is working in the "WIND ON" mode. If not, start it following the instructions in How to restart Aspirin.

Final check of radio pointing offsets in DASH345 and BAND8†

Execute the following loop at each of Saturn's ELs = ~30±10, ~45±10, ~60±10 and ~70±10.
#ref(): File not found: "sat20170707.png" at page "Observing Log/2017-06-30"

Tune DASH345
- Tuning of DASH345/BAND8 for continuum observations
Adjust pointing toward Saturn with DASH345
```
aste17:sbref/stx5d3.start
```
- Record resultant pointing offsets.
Just measure pointing offsets toward Saturn with DASH345 (don't adjust)
```
aste17:radpon/istx5d3.start
```
Tune BAND8
Just measure pointing offsets toward Saturn with BAND8 (don't adjust)
```
aste17:radpon/istx5b8.start
```
- Record the measured pointing offsets of the last AZ and EL scans.

If pointing offsets (daz+ddaz and del+ddel) fluctuate by larger than 8" within a day, restore previous version at the end of the day.
- Previous KISA files
```
DASH345: DASH3.170510
BAND8:   BAND8.170509
astecntl@aste-1c $ cd /cosmos3/aste/etc/kisag
astecntl@aste-1c $ ln -sf DASH3.170510 DASH3
astecntl@aste-1c $ ln -sf BAND8.170509 BAND8
```
