Cross matching is a non trivial problem in itself. We assume cross matching happens off line and there exists an indexing scheme by which catalogs know the exact cross matched tuples
Portion of the sky observed by SDSS
Cross Matching is an inherently difficult problem for the astronomy catalogs
We assume data sets are cross matched and this computation is done offline
This is a strong assumption and often may not be acceptable to astronomers
- try a larger subset of the data from both catalogs
Observed features – radius, mean surface brightness and central velocity dispersion
A two dimensional plane in the observed space of 3D parameters exist called
THE FUNDAMENTAL PLANE
An illustration of the Fundamental Plane interested in ?
Reasonably close recreation of the Fundamental Plane from two cross matched data sets in the centralized setting
Architecture of the Proposed System
QUESTIONS ? interested in ?
