CSV2016: Subref tilt offsets of DASH345/BAND8 (2016-08-26)†

Tasks†

• 220GHz opacity <= 0.07 -> Subref tilt offsets in BAND8
• 220GHz opacity > 0.07 -> Subref tilt 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

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

Information†

• Observers: Kamazaki
• Site: Mitaka
• Weather conditions (2016-08-25T23:36)

  Temperature: -0.33 C
  Humidity: 0.70 hPa
  Wind: 4.10 m/s (259 deg)
  220GHz opacity: 0.0273

220GHz opacity <= 0.07 -> Subref tilt offsets in BAND8†

Preparation†

1. Basic checks
   • KISA files

     [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

   • All subref parameters are zeros
   • Aspirin is ok

     Current time = 2016/08/25 23:57:00
     Aspirin time = 2016/08/25 23:56:58
     Weather time = 2016/08/25 23:56:50
     Aspirin Offset : (Az, El) = (   3.20,  -5.26 )
     Aspirin status : ** WIND ON ** ( C22:on  C6:OFF WIND:on )
     Refraction Corr. status : OK
