We are pleased to announce an important new feature in the Optical Data Centre, released today! These features are powered by Data Central.

The Optical Data Centre (ODC) is a collaboration between AAO-Macquarie University, Australian National University and NCI. It is funded under the Astronomy National Collaborative Research Infrastructure Strategy (NCRIS) Program via Astronomy Australia Ltd (AAL).

The feature is the Simple Spectrum Access service, an IVOA standard which allows you query for spectra held within the ODC. You can filter your queries using a large range of parameters. Documentation can be found here: https://protect-au.mimecast.com/s/bDDFC91WPRTlYRBXToSAuv?domain=docs.datacentral.org.au

We have put together a set of detailed examples, including python scripts that use the new SSA service, as well as the existing Simple Image Access service and the Data Central API. See these pages for details: https://protect-au.mimecast.com/s/ZAatC0YKPvi7rJ35fD0zf8?domain=docs.datacentral.org.au

Some examples include:

1. An interactive GALAH DR3 plot with selected star and its spectra (link).<https://protect-au.mimecast.com/s/K1ayCgZ0N1ioYP2Rf2MpJP?domain=docs.datacentral.org.au>

2. Example output of the example script to access Wigglez spectra (link)<https://protect-au.mimecast.com/s/ZVgwCjZ1N7iBylqXh7a187?domain=docs.datacentral.org.au>

3. Gaussian fits to the emission line CIV 1550 in SVA1_COADD-2939691708 (link)<https://protect-au.mimecast.com/s/MloXCk81N9tKqYQjUJJ0Kx?domain=docs.datacentral.org.au>
[cid:C647A1EF-38CF-40DC-8676-00DDE19547D1 at aao.gov.au]

We are also progressively adding new data, including: the WiggleZ final data release and the Millennium Galaxy Catalogue (latter coming soon).

A reminder also, that the Optical Data Centre can host private data, so you can share and query data within your team, or test out a new data release before it becomes public!

We are working on several other great new features to be released in the coming months!
