Step 1: Preparing observations†
Observation operation 🔒†
- If you face difficulties in ASTE operation during your observations, please look at this page.
Data delivery†
Data reduction†
- CASA is used to reduce position switching and on-the-fly observations with XFFTS.
- NEWSTAR is available for position switching observation data with MAC and WHSF.
- Here are links to relevant pages provided by Nobeyama Radio Observatory (NRO).
- NOSTAR, an IDL based package developed at Nobeyama Radio Observatory, is prepared for on-the-fly observation data with MAC and WHSF.
