CSV2016: Radio pointing offsets of DASH345/BAND8 (2016-09-17)†

Tasks†

• 220GHz opacity <= 0.07 -> Radio pointing offsets in BAND8
• 220GHz opacity > 0.07 -> Radio pointing 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 Sep 15 05:04 /cosmos3/aste/etc/kisag/BAND8 -> BAND8.160913
   lrwxrwxrwx 1 astecntl astctl 12 Sep 15 05:04 /cosmos3/aste/etc/kisag/DASH3 -> DASH3.160913

   • Check all subref parameters (dx,dy,dz,dtx,dty,dtz) are zero
   • Check Aspirin is working in the "WIND" mode
2. Tuning at EL=60.0 deg
   • Tuning of DASH345/BAND8 for continuum observations
   • Don't forget to record weather conditions

Radio pointing offsets of DASH345/BAND8†

• Its instruction is HERE

1. Repeat cross scans toward Saturn and shots of a star one after the other
2. Data reduction
   • Still under preparation

Radio pointing offsets in BAND8†

• 220GHz opacity ~ 0.07

KISA files†

• KISA files -> ok

  [aste16@aste-ms1 ~]$ ssh astecntl@aste-1c "ls -l /cosmos3/aste/etc/kisag/{DASH3,BAND8}"
  lrwxrwxrwx 1 astecntl astctl 12 Sep 15 05:04 /cosmos3/aste/etc/kisag/BAND8 -> BAND8.160913
  lrwxrwxrwx 1 astecntl astctl 12 Sep 15 05:04 /cosmos3/aste/etc/kisag/DASH3 -> DASH3.160913

OPT check†

• Initialization -> ok

  [aste16@aste-ms1 ~]$ ~/analysis/bin/optinit.sh 
  device:    [ ok ]
  mmap:      [ ok ]
  init bcr:  [ ok ]
  init:      [ ok ]
  initLUT:   [ ok ]
  clear FB:  [ ok ]
  AVME-338B -> successfully initialized

• Star image -> ok

  [aste16@aste-ms1 ~]$ ~/analysis/bin/optshot.sh r  1  128
  * image plane = r -> offset=0
  * # of frames = 1 
  * frame capture delay = 1 (sec)
  * fov = blc(192, 192) - trc(319, 319)
  001 [2016-09-14T23:17:14]: max,min,mean,sdev =  86  28 61.181 7.099
  -rw-r--r-- 1 aste16 astgrp 16384 Sep 14 23:17 /var/tmp/opt_aste16.raw

Tuning†

• BAND8

  [asteobs@aste-1c ~]$ swbox_ctl_be CONT
  [asteobs@aste-1c ~]$ swbox_ctl_be     
  status: swbox_ctl_be CONT
