CSV2016: Subref position offsets of DASH345 (2016-08-17)†

Tasks†

• Subref beam maps to estimate rough offsets in DASH345
   

Preparations†

1. 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
2. Tuning at EL=60.0 deg
   • Tuning of DASH345/BAND8 for continuum observations
   • Don't forget to record weather conditions
3. Pointing toward Saturn

   DASH345: stx5d3.start

4. Z-axis adjustment using Saturn

   DASH345: stsbd3z.start

   • Measurement and analysis for single-beam receivers
   • Add a resultant offset to dz (if |dz| > 0.1 mm)

Subref beam maps to estimate rough offsets of DASH345†

1. Take a map of Saturn with (dx,dy)=(0,0),(-1,0),(+1,0),(0,-1),(0,+1)
   • Set (dx,dy) in the subref offset GUI
   • Pointing toward Saturn

   DASH345: stx5d3.start

   • Map of Saturn

   DASH345: str02d3.start

2. Data reduction
   • Make Saturn maps from the CH1 data of the mapping observations with cont
   • Measurement and analysis for single-beam receivers

• UT01:40 qlookc was NOT updated
  • It looked to be due to some connection failures between the ASTE site and Mitaka. After restarting /cosmos3/aste/rc3.d/S98astqlcsv on aste-mt1, this was resolved.
