Query & Download request
Query interface
Source name, RA/Dec, Galactic, Frequency, band, bandwidth
Project code/title, PI name etc.
https://almascience.nao.ac.jp/alma-data/archive
Query results
integration, release date, resolution,
etc.
Imaging products &
raw data can be
downloaded
Recent updates (1)
Enhanced search parameters
Galactic coordinates,
PI & Co-Is names,
Bibcode, sensitivity,etc.
Recent updates (1)
Enhanced query parameters
more than one sources

Line & Cont. Sensitivities
• Line sensitivity (per 10 km s-1) and
continuum sensitivity (aggregated band- width) will be shown in results (optional)
– search by sensitivity is also available
• caveats
– not an actual sensitivity, but the theoretical values are shown. flagging (e.g. shadowing) and other effects are not considered at all – 7-m array: not an actual PWV, but the typical
one according to frequency, is adopted
Tips & Tricks
More columns & re-order them
• On the results page click “more columns”, then check the entries and re-order them

Bug-fixes
• Now they work properly
– Largest angular scale – publication count
– line/continuum sensitivities – footprints
• Sincerely apologize for inconvenience until now
You may encounter …
Please reload the page

Browser recommendation
• We recommend to use
Firefox
for browsing the ALMA Archive
• might be problematic with the others including Chrome, Safari, Edge, Vivaldi, etc.
– e.g. browser crush
