General information†

Schedule†

Account and project†

• Group: asteXX=aste17
• Project:
  • optpon : global pointing with OPT
  • opttrk : continuous tracking with OPT
  • sbrfXX=sbrf16: subref position offsets
  • calibXX=calib16: calibrator survey
  • radpon : radio pointing offset from OPT
• Computers

  Mitaka	aste-mt1	aste-ms1	aste-ms1, aste-mx3

Cautions on operations†

• aste-c1c (= aste-cabin1c)が応答しない
  • OPTを使用した測定の場合、aste-c1cからOPTを制御する必要があります。しかし、aste-c1cが原因不明の理由で落ちていることがあります。この場合、下記の手順で対処して下さい。手助けが必要な場合はComputingにご連絡下さい。
  • aste-c1cにコンソールログインし、状態を確認する

    > ssh asteobs@aste-1c
    > ssh asteobs@tslinux
    Serial Console Server Connection Menu for your Master Terminal Server
    
    1 aste-1s          2 aste-1c          3 aste-2c          4 aste-3c        
    5 aste-v1c         6 aste-c1c         7 aste-r1c         8 ttyS8          
    
    Type 'q' to quit, a valid option[1-8], or anything else to refresh : 6    <--- select "6" for aste-c1c

    • Pattern A: aste-c1c is down and its power-cycle is required, if nothing is displayed after the following messages

      Entering character/text Mode
      Escape character is ^] 
      

    • The way to power-cycle aste-c1c

      [asteobs@aste-1c ~]$ tap_lt1500.py lantap0 1 off
      POS=100,100,100,100
      POF1
      POS=000,100,100,100
      (wait for about 10 seconds)
      [asteobs@aste-1c ~]$ tap_lt1500.py lantap0 1 on 
      POS=000,100,100,100
      PON1
      POS=100,100,100,100

    • The following messages will start after the power-cycle

      screen not found.
      Can't open input device.
      Keyboard not present.  Using ttya for input and output.
      
      FORCE,CPU-50(UltraSPARC-IIi 333MHz), No Keyboard
      OpenBoot 3.10.10, 256 MB memory installed, Serial #9220825.
      Ethernet address 0:80:42:10:43:4c, Host ID: 808cb2d9.
      ...
      aste-cabin1c console login: 
      (It will take about 1-2 minutes after the power-cycle until the login prompt is displayed.)

    • Pattern B: aste-c1c went down and restarted. But, it stopped on the way. Just type "boot".

      ok

      ok boot    <--- Just type "boot"
      ...
      aste-cabin1c console login:

    • Pattern C: aste-c1c is ready and nothing is required for it. Something could be wrong with your login method to aste-c1c. Recheck it.

      aste-cabin1c console login:

  • Don't forget to logout from aste-c1c by "C-]" and also, tslinux by "q"
• 連続波QLOOKは観測終了毎にSTOPに戻りますので、観測開始する毎にSTARTを押して下さい。

Basic procedures†

Start and stop†

• Observing with ASTE (google)
• Useful shortcuts

Tuning of DASH345/BAND8 for continuum observations†

1. Set antenna EL angle to 60 degrees
2. Login to aste-1c with asteobs

   > ssh asteobs@aste-1c

3. Select CONT BE

   asteobs@aste-1c: swbox_ctl_be CONT           <--- CONT BE is selected
   asteobs@aste-1c: swbox_ctl_be
   status: swbox_ctl_be CONT

4. Select either of DASH345 and BAND8 and then, set the frequency of the synthesizer B

Tuning of DASH345/BAND8 for line observations†

• Follow the procedures described in ASTE (google)>Observing with ASTE>Observations>Tuning
