The purpose of this page is to come up with a good wishlist for the folks who are designing the LSST database interface. After our original discussions, we came up with the following list of possible queries:
- Having cutout images be one of the possible outputs returned by a database query
- Being able to get difference images
- Having a simple query to identify groups of galaxies
- Selecting on blended blue light next to red light.
- Having the database be able to do a match on objects detected in previous surveys (e.g., SDSS)
Note that these were queries in addition to those already listed on the web site at http://lsstdev.ncsa.uiuc.edu:8100/trac/wiki/dbQueries
Phil has had some discussions with Jacek at the all-hands meeting and Jacek wants to know about "hard" queries. His example was:
- given this interesting light curve, find all objects with a similar light curve
So, let's not be restricted by what we think the limitations of the database interface may be!
The organisation of this page is as follows. Each science project in the SL chapter of the Science Book will need a technical feasibility study. Since ALL LSST science projects will begin with a database query, it makes sense to focus the feasibility study on what we require from the databases. This can start qualitative and idealised, and then become more focused as we work with the Data Management team. While the science projects are still under discussion, let's keep everything on this (very long!) page, and we'll reorganise later.
