CSV2016: Subref tilt offsets of DASH345/BAND8 (2016-08-30)†

↑

Tasks†

↑

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
↑

Subref tilt offsets in DASH345/BAND8†

  1. Repeat cross scans toward Saturn with various (dtx,dty)
    • Pointing toward Saturn 
      BAND8:   stx5b8.start
DASH345: stx5d3.start
    • Repeat cross scans toward Saturn using the batch mode 
      BAND8:   ststb8.list (NOT stsbb8.list)
DASH345: ststd3.list (NOT stsbd3.list)
      • Don't forget to turn on auto-pointing in the QLOOKC GUI
      • Set AVERAGE = 1 in the QLOOKC GUI
  2. Data reduction
    • Still under preparation
