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

↑

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
  1. Pointing toward Saturn 
    DASH345: stx5d3.start
  2. Z-axis adjustment using Saturn 
    DASH345: stsbd3z.start

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...

    • Check all subref parameters (dx,dy,dz,dtx,dty,dtz) are zero
    • Check Aspirin is working in the "WIND ON" mode
      • Aspirin time was not updated.
      • Restart COSMOS at ASTE site 
        ssh -t aste-1c "sudo /cosmos3/naoj/sbin/cos3_cntl restart all"
      • Restart connection from remote site to ASTE site 
        ssh -t aste-mt1 "sudo /cosmos3/naoj/sbin/cos3_cntl restart"
      • Turn on Aspirin-blue (wind correction) 
        ssh aste-1c "/cosmos3/naoj/bin/windsw on"
  2. Tuning at EL=60.0 deg
