The Rubin Science Platform (RSP), described in \citeds{LSE-319}, is a set of integrated web-based applications, services, and tools that provides access to the Rubin data products and enables next-to-the-data analysis.
15
15
The RSP comprises three different ``Aspects'': a \emph{Portal} Aspect designed to provide an environment for data discovery, query, filtering, and visualization, a \emph{Notebook} Aspect to enable next-to-the-data analysis, and an \emph{API} Aspect for programmatic access to the Rubin data products via Virtual Observatory (VO) interfaces.
16
16
The Portal and Notebook Aspects of the RSP make use of the same APIs as the API Aspect to internally access the LSST datasets.

During the commissioning period, Rubin will work with the Community Brokers to integrate them \citedsp{rtn-010}.

Both Alert Production and Solar System Processing depend on the existence of template images.
15
15
During steady-state operations, these templates will be constructed during the annual Data Releases and will be built from the best available subset of images taken.
16
16
To enable alert production to proceed during commissioning and early operations, it is necessary build templates incrementally as data become available, as recommended by the study described in \citeds{DMTN-107}.
17

Because we have a smaller set of input images to choose from and uncertain knowledge about future observations, incremental template generation necessarily must balance the tradeoff of earlier template availability against template quality and spatial completeness.

Scientifically it is important that once a template is constructed for a given region of sky, it is used exclusively until it can be updated in the next Data Release.
22
22
Repeated changes to the template make it extremely difficult to construct usable lightcurves for objects from individual difference image sources: transient objects such as supernovae will be contaminated by changing flux levels from the evolving template, and variable objects such as variable stars and AGN will require repeated corrections for different template flux levels as well.

ComCam is Rubin's engineering camera that is used for testing and validating the observatory's systems and processes prior to installation of the LSST Camera.
Rubin Observatory will work closely with the Survey Cadence Optimization Committee (SCOC) and Community on the detailed design of the Early Science Program.
Recommendations will take into account the plans for commissioning and the realized performance of the telescope and software, and should align as closely as possible with those of the main survey and ultimate long-term science goals.
