CSV2016: Subref position offsets of DASH345 (2016-08-18)

CSV2016: Subref position offsets of DASH345 (2016-08-18)†

↑

Tasks†

Subref position offsets in DASH345

↑

Preparations†

Basic checks

Record which kisa files are used for DASH345 and BAND8

aste16@aste-ms1: ssh astecntl@aste-1c "ls -l /cosmos3/aste/etc/kisag/{DASH3,BAND8}"
lrwxrwxrwx 1 astecntl astctl 12 Jun  3  2015 /cosmos3/aste/etc/kisag/BAND8 -> BAND8.150603
lrwxrwxrwx 1 astecntl astctl 12 Jun  1  2015 /cosmos3/aste/etc/kisag/DASH3 -> DASH3.150601

Check all subref parameters (dx,dy,dz,dtx,dty,dtz) are zero
Check Aspirin is working in the "WIND ON" mode

Tuning at EL=60.0 deg
- Tuning of DASH345/BAND8 for continuum observations
- Don't forget to record weather conditions

Pointing toward Saturn
```
DASH345: stx5d3.start
```
Z-axis adjustment using Saturn
```
DASH345: stsbd3z.start
```
- Subref z-position offsets>Measurement and analysis for single-beam receivers
- Add a resultant offset to dz (if |ddz| > 0.1 mm)

↑

Subref offset positions in DASH345†

Repeat cross scans toward Saturn with various (dx,dy)
- Repeat cross scans toward Saturn using the batch mode
```
DASH345: stsbd3.list
```
- Don't forget to turn on auto-pointing in the QLOOKC GUI
Data reduction
- Still under preparation...

Check all subref parameters (dx,dy,dz,dtx,dty,dtz) are zero
Check Aspirin is working in the "WIND ON" mode
- Aspirin time was not updated.
- Restart COSMOS at ASTE site
```
ssh -t aste-1c "sudo /cosmos3/naoj/sbin/cos3_cntl restart all"	
```
- Restart connection from remote site to ASTE site
```
ssh -t aste-mt1 "sudo /cosmos3/naoj/sbin/cos3_cntl restart"
```
- Turn on Aspirin-blue (wind correction)
```
ssh aste-1c "/cosmos3/naoj/bin/windsw on"
```
