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

Tasks†

• Subref position 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

1. Pointing toward Saturn

   DASH345: stx5d3.start

2. 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†

1. 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
2. Data reduction
   • Still under preparation...
