<h2>Data Products</h2>
<p>Below you will find information of the pixel data products that will be produced by the LSST software stack.
As well, you will find information on the potential added value user-generared products the SSSC is planning as well as the data products to be provided by the LSST project calculated via the LSST stack.</p>
</header>
<p> <h2> How Rubin Observatory Approaches LSST Solar System Processing Data Products</h3>
<p> The goal is to provide products to the community that enable science in four guiding science themes; making a census of the Solar System is one of the four. LSST project therefore design products that are:
<ol>
<li> Broadly useful for delivering unique LSST-enabled science
<li> Capture aspects that the LSST team is uniquely position to deliver
</ol>
<p> <H2> Key LSST Project Deliverables for Solar System Science </H2>
<ul>
<li> <b> Within 60 seconds of each observation: </b> A real-time stream of observation reports (alerts) with information about astrometry, photometry, and shape including trailing, direction of motion. </li>
<li> <b>Every day: </b> A stream of linked tracks reported to the <a href="https://www.minorplanetcenter.net/">Minor Planet Center (MPC)</a>. </li>
<li> <b> Every day:</b> A catalog of orbits for LSST-discovered objects. </li>
<li> <b> Annually: </b>Precisely calibrated photometric catalog (ugrizy bands) accurate to 5 mmag (systematics limited), with every data release. </li>
</p>
<p>**The observatory code assigned by the MPC for the Simonyi Survey Telescope at Rubin Observatory (the main 8.4m telescope). The code is X05 and is further details are available in the MPC's <a href="https://minorplanetcenter.net/iau/lists/ObsCodesF.html"> observatory codes list </a>.** </p>
<p> A short overview of Rubin LSST Solar System data products can be found <a href="https://docushare.lsst.org/docushare/dsweb/Get/Document-29545" target="_blank"> here </a>. <a href="https://docushare.lsstcorp.org/docushare/dsweb/Get/LSE-163/">The Data Products Definition Document (DPDD) </a> defines what the nightly and yearly catalogs will contain. You can find a handy outline of the proposed database schema for the LSST SSObject table <a href="https://docushare.lsstcorp.org/docushare/dsweb/Get/LSE-163/">here</a> .

<h2>LSST Project Data Product Levels</h2>
The LSST stack will produce data products at three levels, which are broadly defined below. <br> <br>
<p><strong>Prompt</strong> data products produced on nightly or shorter timescales which will consist of basic images, source catalogs, transient identifications, moving object identifications, and event alerts.</p>
<p><strong>Data Release </strong> annual data release products including refinements to calibrations and photometry, calibration images, image co-adds and catalogs. </p>
<p><strong>User Generated/Added Value</strong> are user-generated added value products.</p>
<p> Exactly what parameters will be automatically provided within Prompt and Data Release products are still being discussed. You can learn more about the current status on planned Solar System Data Products from LSST in this <a href="https://www.youtube.com/watch?v=nSUTitsqdJ0">recorded presentation </a> by Mario Jurić.
More information on all LSST data products can be found <a href="https://www.lsst.org/about/dm/data-products">here.</a></p>
<p> Annual release will have all LSST observations run through one version of the LSST data pipelines. The version of software run on the nightly observations can change, and old observations won't be rerun through the updated pipelines until the annual release.

<p> Additional information on LSST data processing pipelines and data products can be found on the <a href="https://www.lsst.org/scientists/">LSST Information for Scientists page</a>.
<H2> The LSST Alert Stream </H2>
<p> After an LSST image is taken, the image subtraction pipeline will identify transient sources
(stuff that moves or varies in brightness). These Difference Image Analysis Sources (DIASources) will be
sent out in the public LSST Alert Stream within 60s of the observation's end.

<h2> Rubin Data Products Abridged September 2022 </h2>
<p> Slides from this presentation can be cited and found <a href="https://www.lsst.org/about/dm/data-products"> here </a>.
<h2> DP0.3 Simulated Rubin Solar System Data Products </h2>
<p> On the Rubin Science Platform (RSP), LSST data rights holders can test software and database queries with DP0.3, simulated Rubin Solar System Data Products. The RSP has both a jupyter notebook environment, a data portal environment, and API programmatic access.
DP0.3 was generated by members of the Rubin Solar System Pipelines and Commissioning teams, with help from the SSSC. Further details on DP 0.3 including tutorials and getting access to the RSP, can be found <a href="https://dp0-3.lsst.io/">here</a>. </p>
<h2> Early Science and Year One Data Products </h2>
<p> "Early Science is defined as any science enabled by Rubin for its community through and including the first data release, Data Release 1 (DR1)." - Leanne Guy Rubin Observatory Data Management Scientist and Interim AD for System Performance. </p>
<p> Rubin Observatory has released the <a href="https://rtn-011.lsst.io/">Rubin Observatory Plans for an Early Science Program </a> document. This is a living doocumentation outlining the plan for commissioning observations, draft plans for Year 1 science operations, and plans for alert production in the first year of LSST.
A summary presentation of the contents of this document was presented in October 2022 and available online <a href="https://community.lsst.org/uploads/short-url/Ah3WdEGm0Yw9rPUqWBeJp2tS0K0.pdf">here</a>. </p>
<h2> Proposed Rubin-Euclid Joint Data Products </h2>
There is on-going discussion about some joint Rubin-Euclid data products, including Solar System data products, that would be available to both surveys' data rights holder. A document with initial recommendations from the joint Rubin-Euclid working group is available <a href="https://arxiv.org/abs/2201.03862">here</a>.

<h2> Expected Advanced LSST/User Generated Data Products Useful for Solar System Science </h2>
<ul>
<li>Where in the sky LSST is expected the next night will be accessible via an API/software routine. One can estimate for new Solar System discoveries whether LSST will be able to do self follow-up. </li>
<li> SSSC members are working on a dedicated code to identify nightly tracklets from streaks and submit those to the MPC. </li>
</ul>
<h2>Proposed SSSC Generated Solar System-Specific Data Products</h2>
<p> More information of proposed SSSC user-generated data products and software can be found in our <a href='https://iopscience.iop.org/article/10.3847/2515-5172/ab0e10'>software roadmap </a>,
