Rubin Observatory Plans for Early Science v7.0 released

News
#1

Rubin Observatory Plans for Early Science : RTN-011, v7.0, has been issued. We now have Rubin DOIs and so the document should be cited as: Rubin Observatory Plans for an Early Science Program

This version of RTN-011 contains several updates:

  • Update to the Data Preview and Release schedule, stating that DR1 will now be based on 1 year of LSST data, not 6 months.
  • Details of the LSSTCam commissioning data that will form the basis for DP2,
  • Details on the timeline early alert stream,
  • Description of the early prompt image and catalog data products that can be expected in 2026.

The release date for DP2 will be in mid 2026. and access will be via the RSP at data.lsst.cloud.

Another update, v7.1 will be issued following the freeze of the DP2 processing pipelines in early December, when we expect to be able to give more details on the contents of DP2.

Questions are always welcome here and in Support

So do I understand this correctly?

There will be single visit images and source catalogs (“early prompt image and catalog data”) released in the two years leading up to DR1? Not just difference detections?

If this is correct, I’d like to thank everyone that supported that decision and more importantly, I thank the people will have to carry it out! Even single visit depth enables of a lot of science.

Yes, this is correct – single visit images (PVIs) and per-epoch Source catalogs.

The full history of the change is on RFC-938 if you are interested.

Thanks for the update! In Fig 1 of RTN-011, it indicates that DR1 will be released at the “start of year 2” (so ~end of 2026-early 2027) and include the first 6th months of data. In this post you mentioned that it’ll include the first year of data, so presumably be released later. Can you clarify and approximately when is DR1 expected?

Hi,

Is there an estimate for the data volume of DP2?

In particular, is there an estimate for the data volume of the coadd catalogs, or at least the number of objects in the coadd catalogs?

Thanks,
SG

Or more-or-less equivalently: what is the total area? 3000 square degrees?

Thanks,
SG

I should be able to provide an estimate for that at the 11 Dec Science Assembly (and RTN-011 update).
