CSV2016: Long time integration in DASH345/BAND8 (2016-09-10)†

↑

Tasks†

Long time integration in DASH345/BAND8

↑

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" mode

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

Radio pointing offsets of DASH345/BAND8†

Its instruction is HERE

Repeat cross scans toward Saturn and shots of a star one after the other
Data reduction
- Still under preparation

Information†

Observers: Izumi
Site: Mitaka

Weather conditions (2016-09-09UT00:00)

Temperature: -1.43 C
Humidity: 0.45 hPa
Wind: 3.09 m/s (208 deg)
220GHz opacity: 0.0156

220GHz opacity <= 0.07 -> Radio pointing offsets in BAND8
