Observing Log

CSV2017: Remaining CSV tasks†

Tasks†

• Final check of radio pointing offsets in BAND8 and DASH345 (1 day)
  • Their KISA files were updated on June 1st. Confirm
• Test observations with WHSF and MAC (1.5 day)
• Tsys measurements in BAND8 and DASH345 (0.5 day)
  • Tune the receivers at the following LO frequencies at EL=60 and measure Tsys.
  • Adjust the receivers if necessary

Preparations†

1. Basic checks
   • Make sure that DASH3 and BAND8 are linked to the following files

     [aste17@aste-ms1 ~]$ ssh astecntl@aste-1c "ls -l /cosmos3/aste/etc/kisag/{DASH3,BAND8}"
     lrwxrwxrwx 1 astecntl astctl 12 May  9 11:27 /cosmos3/aste/etc/kisag/BAND8 -> BAND8.170509
     lrwxrwxrwx 1 astecntl astctl 12 May 10 14:31 /cosmos3/aste/etc/kisag/DASH3 -> DASH3.170510

     • If not, please contact with CSV lead.
   • Set all subref parameters (dx,dy,dz,dtx,dty,dtz) zeros in the subref offset GUI.
   • Confirm that Aspirin is working in the "WIND ON" mode. If not, start it following the instructions in How to restart Aspirin.
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†

• Repeat

1. Tune DASH345
2. Adjust pointing toward Saturn
   • Record resultant pointing offsets
3. Tune BAND8
4. Measure pointing toward Saturn (don't adjust)
   • Record pointing offsets

1. Its instruction is HERE
   • Observation tables for "Check OPT images"

     radpon/t125-09C.start

   • The OPT source is "125-09C".
   • It is UNNECESSARY to adjust focus of OPT.
   • If aste-c1c does not respond, power-cycle it. Its instruction is No response from aste-c1c in FAQ/Known issues.
   • Continue the measurements until Jupiter's EL angle becomes less than 25 degrees.
2. Data reduction
   • Try to reduce taken data following Radio pointing offsets - Analysis
