CSV2016: Subref position offsets of DASH345 and BAND8 (2016-08-15)†

Tasks†

• Subref beam maps to estimate rough adjustments of DASH345 and BAND8
  • 220GHz opacity <= 0.07 -> BAND8
  • 220GHz opacity > 0.07 -> DASH345

1. Preparations
   • 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
   • Don't forget to record weather conditions
3. Pointing toward Saturn

   BAND8:   stx5b8.start
   DASH345: stx5d3.start

4. Z-axis adjustment using Saturn

   BAND8:   stsbb8z.start
   DASH345: stsbd3z.start

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

   BAND8:   stx5b8.start
   DASH345: stx5d3.start

   • Map of Saturn

   BAND8:   str02b8.start
   DASH345: str02d3.start

6. Data reduction
   • Make Saturn maps from the CH1 data of the mapping observations with cont
