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
