CSV2016: Subref tilt offsets of DASH345/BAND8 (2016-08-25)†

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: Izumi
• Site: Mitaka
• Weather conditions (2016-08-25T:0130)

  Temperature: -3.93 C
  Humidity: 0.82 hPa
  Wind: 1.76 m/s (251 deg)
  220GHz opacity: 0.0499

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

Measurement Log†

Preparation†

1. Basic checks
   • Record which kisa files are used for DASH345 and BAND8

   • Check all subref parameters (dx,dy,dz,dtx,dty,dtz) are zero
   • Check Aspirin is working in the "WIND ON" mode
     =>Aspirin monitor: weather 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"

       =>weather time was not fixed (and changed 1970/01/01 00:00:00 ??)

       #ref(): File not found: "Aspirin-20160825.png" at page "Observing Log/2016-08-25"

     • Restart Envmon/Aspirin on aste-v1c

       ssh aste-v1c "/opt/sudo/bin/sudo /cosmos3/naoj/rc3.d/S99astnaojd stop; nohup /opt/sudo/bin/sudo /cosmos3/naoj/rc3.d/S99astnaojd start"

     • Restart Aspirin on aste-1c

       ssh -t aste-1c "sudo /cosmos3/naoj/rc3.d/S99astnaojd stop; nohup sudo /cosmos3/naoj/rc3.d/S99astnaojd start"

       =>weather time was not fixed
     • Restart aste-1c
       =>weather time was fixed but c22 was off (Aspirin status: wrong, connection inactive)

     • Restart aste-v1c
       =>All problem was resolved
     • Turn on Aspirin-blue (wind correction)

       ssh aste-1c "/cosmos3/naoj/bin/windsw on"
